Answer 1

#1
x^2+2x+4 can be written as
x^2 + x(2) + 4*1^2
I think that the best choice would be
1 big square, 1 tall rectangle, 4 little squares

#2
–3f^2 + 4f – 3 + 8f^2 + 7f + 1
just collect terms of the same power
(-3+8)f^2 + (4+7)f + (-3+1)
5f^2 + 11f - 2

#3
(2x^2 + 6x + 1) + (–7x^2 + 2x – 3)
(2-7)x^2 + (6+2)x + (1-3)
-5x^2 + 8x - 2

#4
(3x^2 – 7x – 4) – (6x^2 – 6x + 1)
(3-6)x^2 + (-7+6)x + (-4-1)
-3x^2 - x - 5

#5 just add up the sides
2x+3x+4x+1+4x+1
13x+2

#6
(5x^2 – 7x – 6)-(8x^2 + 6x – 1)
(5-8)x^2 + (-7-6)x + (-6+1)
-3x^2 - 13x - 5

#7 ok
#8 ok

#9 the number must be <b>less than</b> 10, so instead of 10*10^7 you want 1 * 10^8.

Answer 2

the first four were wrong, it was:

#1: B
#2: C

Answer 27

Hey guys! Okay, so I'm pretty sure that if you are smart, you would know that the person under the name "Ms. Sue" isn't Ms. Sue because we also know that she would never give out answers just like that! Plus, there isn't an emoji beside her name soooooo..... but anyway, the real question is: Should we care? I'll let it go through your brain for a bit...

Time's up!

The correct answer is "No.". I mean, we got the help that we needed so just let it be and move on with your lives. I'm pretty sure that you aren't depressed enough to talk about if the "Ms. Sue" is real or not. That's all for today folks!

@Some Random Girl, I love reading your responses. You are amazing! If I want to laugh after a long hard day, I come here and just read what you have to say. You are witty, and I love that you are yourself even if it's on a screen. You don't care what people think of you. Sounds like me... Maybe you should hang out with my brother. Maybe he'll get your attitude. Seriously, he lets everyone walk all over him, it ticks me off. Anyway, your cool.

do u like dog aswell

Answer 44

For why the equal to 511 they are equal to 511 because all the equations add up to 511.

Answer 45

The reason I cheat is because I am stupid and this school has not taught me anything so I have to cheat period

Answer 46

hamburgmer

Answer 47

Ok so "Ms. Sue" Im confused as Hell so I thought These "*" meant multiplication but from my (confused) mind you used them for addition in your equations. yes...no? Like tf Im stupid so I need an explanation rn.

Answer 48

*Like tf Im stupid so..."

Answer 49

@Max fr bc if you add them it'll equal the same thing so why "*" that usually means multipication but it wouldnt make sense and they could put "x"

For number 10 you just need to figure out the different ways you can get 5^11.
For example, everyone should have this one: 5*5*5*5*5*5*5*5*5*5*5.
Good luck. :)

Answer 84

you guys are losers. All of these are incorrect

Answer 85

To write 511 as the product of two powers, we can consider different combinations of prime factors. Here are three different ways to write 511 as the product of two powers:

511 = 7^1 * 73^1
In this expression, 7 is raised to the power of 1, and 73 is also raised to the power of 1. Both numbers are prime factors of 511, and when multiplied together, they result in 511.

511 = 11^1 * 47^1
In this expression, 11 is raised to the power of 1, and 47 is also raised to the power of 1. Similar to the previous example, both numbers are prime factors of 511, and their product equals 511.

511 = 1^9 * 511^0
In this expression, 1 is raised to the power of 9, and 511 is raised to the power of 0. The reason this expression is equal to 511 is because any number (except 0) raised to the power of 0 is defined as 1. Thus, 511^0 equals 1, and 1^9 equals 1. Therefore, the product of 1^9 and 511^0 is indeed 511.

All three expressions are equal to 511 because they represent different prime factorizations of 511. Prime factorization is a unique representation of a number as the product of its prime factors, and since 511 is a composite number (not prime), it can be expressed in multiple ways as a product of powers. Each of the expressions above consists of prime factors of 511, and when these prime factors are multiplied together, the result is 511.

Answer 91

One way to write 511 as the product of two powers is:

7^3 * 1^1 = 343 * 1 = 343

Another way to write 511 as the product of two powers is:

2^9 * 1^1 = 512 * 1 = 512

A third way to write 511 as the product of two powers is:

8^2 * 2^1 = 64 * 2 = 128

All three expressions are equal to 511 because in each expression, one of the powers is equal to 1. This means that only one of the base numbers in the expression is being raised to a non-zero exponent, and the other base number is being raised to a zero exponent. Therefore, when you multiply the two base numbers raised to their respective exponents, you end up with only one non-zero base number that is being raised to a non-zero exponent, and this equals 511.

Answer 92

Three different ways to write 5¹¹ as the product of two powers are:

1. 5¹¹ * 1¹ = 5¹¹

2. 5³ * 5⁸ = 125 * 39,0625 = 5¹¹

3. 5²⁰ * 1⁻⁹ = 95,367,431.64 * 0.000000001 = 5¹¹

All three expressions are equal to 5¹¹ because in each expression, one of the powers is equal to 1 and the other power is raised to a non-zero exponent. When you multiply the two base numbers raised to their respective exponents, you end up with only one non-zero base number that is being raised to a non-zero exponent, and this equals 5¹¹.

Answer 93

To multiply two numbers in scientific notation, you can multiply the coefficients and add the exponents.

So, (2.5 × 10⁴)(4 × 10³) = (2.5 × 4) × 10⁴⁺³ = 10 × 10⁷ = 10⁸

Therefore, (2.5 × 10⁴)(4 × 10³) is equal to 10⁸ in scientific notation.

Answer 95

One way to write 5¹¹ as the product of two powers is:
