***** is my answer
so sorry that i don't know the first few:(
and sorry if the first one is confusing
but pls help asap!
help much apprectiated, thank you:)

@Steve @TTR+S<3 are right!!! Thanks to them I got 100%!

5^11 = 5^3 * 5^8
5^11 = 5^0 * 5^11
5^11 = 5^-4 * 5^15

the first four were wrong, it was:

#1: B
#2: C
#3: B
#4: A

thank you on the others though Steve:)

#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 less than 10, so instead of 10*10^7 you want 1 * 10^8.

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!

Brought to you by "The Random"!

Mac n and Ms Sue are right. and btw there is a fake mrs.sue that post fake answers. That is the real Mrs sue.

btw, I really don't care if I get any thumbs down. At least I know you read it! XD

Thanks Mac N! 9/9 100%

Steve and TTR+S<3 are correct. The answers have NOT moved around...

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. :)

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