a = w * L
so
L = a / w
L = (x^3 - 13 x + 12) / ( x+4)
so divide
x^2 - 4 x + 3 maybe?
so
L = a / w
L = (x^3 - 13 x + 12) / ( x+4)
so divide

bob drove 120 miles on his vacation. he drove an average of 1.2 times faster on the second 60 miles of his trip. Which expression represents the time he spent driving? let x = his speed on the first half of the trip
Bot
Let t be the time Bob spent driving on the first half of the trip, then his speed was x and he covered a distance of 60 miles. The time he spent driving on the second half of the trip would be t/1.2 because he was driving faster. The distance he covered on the second half of the trip was also 60 miles.
Therefore, the total time he spent driving would be:
t + t/1.2
Simplifying, we get:
2.2t/1.2
which can be written as:
1.83t
Therefore, the total time he spent driving would be:
t + t/1.2
Simplifying, we get:
2.2t/1.2
which can be written as:
1.83t

I apologize for the mistake. Here's the correct solution:
Let Bob's speed on the first half of the trip be x. Then, the time he spends on the first half of the trip would be:
time = distance / speed = 60/x
On the second half of the trip, Bob drives 1.2 times faster, so his speed would be:
1.2x
The time he spends on the second half of the trip would be:
time = distance / speed = 60/(1.2x) = 50/x
Therefore, the total time Bob spent driving would be:
60/x + 50/x = 110/x
So, the correct answer is A. 110/x.
Let Bob's speed on the first half of the trip be x. Then, the time he spends on the first half of the trip would be:
time = distance / speed = 60/x
On the second half of the trip, Bob drives 1.2 times faster, so his speed would be:
1.2x
The time he spends on the second half of the trip would be:
time = distance / speed = 60/(1.2x) = 50/x
Therefore, the total time Bob spent driving would be:
60/x + 50/x = 110/x
So, the correct answer is A. 110/x.

simplify x/4x+x^2
Bot
x/(4x + x^2) can be simplified by factoring the denominator:
x/(4x + x^2) = x/(x(4 + x))
Notice that x appears in both the numerator and denominator, so we can cancel them out:
x/(x(4 + x)) = 1/(4 + x)
Therefore, x/(4x + x^2) simplifies to 1/(4 + x).
x/(4x + x^2) = x/(x(4 + x))
Notice that x appears in both the numerator and denominator, so we can cancel them out:
x/(x(4 + x)) = 1/(4 + x)
Therefore, x/(4x + x^2) simplifies to 1/(4 + x).

simplify x/(7x+x^2)
Bot
x/(7x+x^2) can be simplified by factoring the denominator:
x/(7x + x^2) = x/(x(7 + x))
Notice that x appears in both the numerator and denominator, so we can cancel them out:
x/(x(7 + x)) = 1/(7 + x)
Therefore, x/(7x + x^2) simplifies to 1/(7 + x).
x/(7x + x^2) = x/(x(7 + x))
Notice that x appears in both the numerator and denominator, so we can cancel them out:
x/(x(7 + x)) = 1/(7 + x)
Therefore, x/(7x + x^2) simplifies to 1/(7 + x).

simplify -12x^4/(x^4+8x^5)
Bot
-12x^4/(x^4+8x^5) can be simplified by factoring out -4x^4 from numerator and denominator:
-12x^4/(x^4 + 8x^5) = (-4x^4*3)/(x^4*(1 + 8x))
Now we can cancel out -4x^4 from the numerator and denominator:
-12x^4/(x^4 + 8x^5) = -3/(1 + 8x)
Therefore, -12x^4/(x^4 + 8x^5) simplifies to -3/(1 + 8x).
-12x^4/(x^4 + 8x^5) = (-4x^4*3)/(x^4*(1 + 8x))
Now we can cancel out -4x^4 from the numerator and denominator:
-12x^4/(x^4 + 8x^5) = -3/(1 + 8x)
Therefore, -12x^4/(x^4 + 8x^5) simplifies to -3/(1 + 8x).

simplify (x-2)/(x^2+4x-12)
Bot
To simplify (x-2)/(x^2+4x-12), we need to factor the denominator:
(x^2 + 4x - 12) can be factored as (x + 6)(x - 2)
Thus, we get:
(x - 2)/(x^2 + 4x - 12) = (x - 2)/[(x + 6)(x - 2)]
We can cancel out (x - 2) from the numerator and denominator:
(x - 2)/[(x + 6)(x - 2)] = 1/(x + 6)
Therefore, the simplified form of (x-2)/(x^2+4x-12) is 1/(x+6).
(x^2 + 4x - 12) can be factored as (x + 6)(x - 2)
Thus, we get:
(x - 2)/(x^2 + 4x - 12) = (x - 2)/[(x + 6)(x - 2)]
We can cancel out (x - 2) from the numerator and denominator:
(x - 2)/[(x + 6)(x - 2)] = 1/(x + 6)
Therefore, the simplified form of (x-2)/(x^2+4x-12) is 1/(x+6).

simplify (x^2-3x-18)/(x+3)
Bot
To simplify (x^2-3x-18)/(x+3), we can first factor the numerator:
(x^2 - 3x - 18) can be factored as (x - 6)(x + 3)
Thus, we get:
(x^2 - 3x - 18)/(x + 3) = [(x - 6)(x + 3)]/(x + 3)
We can cancel out (x + 3) from the numerator and denominator:
[(x - 6)(x + 3)]/(x + 3) = x - 6
Therefore, the simplified form of (x^2-3x-18)/(x+3) is x - 6.
(x^2 - 3x - 18) can be factored as (x - 6)(x + 3)
Thus, we get:
(x^2 - 3x - 18)/(x + 3) = [(x - 6)(x + 3)]/(x + 3)
We can cancel out (x + 3) from the numerator and denominator:
[(x - 6)(x + 3)]/(x + 3) = x - 6
Therefore, the simplified form of (x^2-3x-18)/(x+3) is x - 6.

1. simplify 3/5a * 1/a^2
2 multiply (x-5)/(4x+8)*(12x^2+32x+16)
2 multiply (x-5)/(4x+8)*(12x^2+32x+16)
Bot
1. simplify 3/5a * 1/a^2:
To simplify this expression, we can combine the two fractions by multiplying their numerators and denominators:
3/5a * 1/a^2 = (3*1)/(5a*a^2)
= 3/(5a^3)
Therefore, the simplified form of 3/5a * 1/a^2 is 3/(5a^3).
2. multiply (x-5)/(4x+8)*(12x^2+32x+16):
To multiply these two expressions, we can first factor out 4 from the denominator of the first fraction:
(x - 5)/(4x + 8) = (x - 5)/4(x + 2)
Now we can cancel out the 4 in both the numerator and denominator of the first fraction and simplify the second fraction:
(x - 5)/(4x + 8) * (12x^2 + 32x + 16) = (x - 5)/(x + 2) * (3x^2 + 8x + 4)
Next, we can factor the second fraction:
3x^2 + 8x + 4 = 3(x^2 + (8/3)x + 4/3) = 3(x + 2/3)(x + 2)
Substituting this back into the expression, we get:
(x - 5)/(x + 2) * 3(x + 2/3)(x + 2)
Now we can cancel out (x + 2) from the numerator and denominator:
(x - 5)/(x + 2) * 3(x + 2/3)(x + 2) = (x - 5) * 3(x + 2/3)
= 3x^2 - 4x - 10/3
Therefore, the product of (x-5)/(4x+8)*(12x^2+32x+16) is 3x^2 - 4x - 10/3.
To simplify this expression, we can combine the two fractions by multiplying their numerators and denominators:
3/5a * 1/a^2 = (3*1)/(5a*a^2)
= 3/(5a^3)
Therefore, the simplified form of 3/5a * 1/a^2 is 3/(5a^3).
2. multiply (x-5)/(4x+8)*(12x^2+32x+16):
To multiply these two expressions, we can first factor out 4 from the denominator of the first fraction:
(x - 5)/(4x + 8) = (x - 5)/4(x + 2)
Now we can cancel out the 4 in both the numerator and denominator of the first fraction and simplify the second fraction:
(x - 5)/(4x + 8) * (12x^2 + 32x + 16) = (x - 5)/(x + 2) * (3x^2 + 8x + 4)
Next, we can factor the second fraction:
3x^2 + 8x + 4 = 3(x^2 + (8/3)x + 4/3) = 3(x + 2/3)(x + 2)
Substituting this back into the expression, we get:
(x - 5)/(x + 2) * 3(x + 2/3)(x + 2)
Now we can cancel out (x + 2) from the numerator and denominator:
(x - 5)/(x + 2) * 3(x + 2/3)(x + 2) = (x - 5) * 3(x + 2/3)
= 3x^2 - 4x - 10/3
Therefore, the product of (x-5)/(4x+8)*(12x^2+32x+16) is 3x^2 - 4x - 10/3.

simplify x/6x-x^2
Bot
To simplify x/(6x - x^2), we can factor out x from the numerator and denominator:
x/(6x - x^2) = x/(x(6 - x))
Now we can cancel out x from the numerator and denominator:
x/(x(6 - x)) = 1/(6 - x)
Therefore, the simplified form of x/(6x - x^2) is 1/(6 - x).
x/(6x - x^2) = x/(x(6 - x))
Now we can cancel out x from the numerator and denominator:
x/(x(6 - x)) = 1/(6 - x)
Therefore, the simplified form of x/(6x - x^2) is 1/(6 - x).
bot?
that isnt the full answer its this one 1/6-x; where x=0,6 or 1/6-x; where x=6
Bot
I apologize for the confusion. You're correct.
The simplified form of x/(6x - x^2) is indeed 1/(6-x), but with the condition that x cannot equal 0 or 6, as that would make the denominator zero.
So the complete answer is:
x/(6x - x^2) = 1/(6 - x), for x not equal to 0, 6.

The time t required to drive a certain distnace varies inversely with the speed, r, if it takes 7 hours the distance at 55 miles per hour how long will it take to drive the same distance at 65 miles per hour
The time t required to drive a certain distnace varies inversely with the speed, r, if it takes 7 hours the distance at 55 miles per hour how long will it take to drive the same distance at 65 miles per hour
Bot
We know that the time t required to drive a certain distance varies inversely with the speed r. We can write this as:
t = k/r, where k is a constant of variation.
We are also given that it takes 7 hours to travel this distance at a speed of 55 miles per hour. We can use this information to find the value of k:
7 = k/55
Multiplying both sides by 55:
k = 385
Now we can use k to find the time required to travel the same distance at a speed of 65 miles per hour:
t = k/r
t = 385/65
t = 5.92 hours (rounded to two decimal places)
Therefore, it will take approximately 5.92 hours to drive the same distance at a speed of 65 miles per hour.
t = k/r, where k is a constant of variation.
We are also given that it takes 7 hours to travel this distance at a speed of 55 miles per hour. We can use this information to find the value of k:
7 = k/55
Multiplying both sides by 55:
k = 385
Now we can use k to find the time required to travel the same distance at a speed of 65 miles per hour:
t = k/r
t = 385/65
t = 5.92 hours (rounded to two decimal places)
Therefore, it will take approximately 5.92 hours to drive the same distance at a speed of 65 miles per hour.
