Question

The width w of a rectangular swimming pool is x+4. the area a of the pool is x^3-13x+12. What is an expression for the length of the pool

If you can help I would really appreciate it

Answer 1

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

TYSM!!! HAVE A GOOD DAY BOTTTT

Answer 26

Bot can you simplify x/6x-x^2

Answer 27

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

Answer 28

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.

Sure, feel free to ask!

Answer 30

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).

Answer 31

You're welcome!

Answer 32

Yes! Please let me know what you need help with.

Answer 33

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).

Answer 34

You're welcome! Let me know if you need help with anything else.

Answer 35

Yes, I can help you! What's the question?

Answer 36

-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).

Answer 37

Sure, what's the question?

Answer 38

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).

Answer 39

No problem, I'll wait for your last question.

Answer 40

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.

Answer 42

Yes! Please list all of your questions and I'll do my best to answer them all.

Answer 43

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.

Answer 45

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).

Answer 46

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.

Answer 47

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.
