X=-24 for number 1
I don't know a single thing about maths(that's a lie, I just suck at it), but there's a general rule that applies here:
"If you don't know what to say, answer A."

That's why I used the smiley, and not stuff like: .
Number 2 is 4Xsquared
And number 3 is C.
Here's one possible solution:

Just say you couldn't do it because THERE'S AN ELEPHANT IN THE WAY!

lmfao man thats so sick and depraved and yet funny all at once

my hats off to you IbanezSA160, you have embodied the Pit into one little poem
the third answer is clearly "C"...however i have no idea about the other ones

Number 1: Multiply 2x-7 by the other denominator (2) and multiply x+2 by the other denominator (5) so you get
4x-14=5x+10
Then you subtract 10 and subtract 4x and you get
-24=x

Done with #1

With that knowledge you can figure out #2.

As for three, set it up like this:

60/220 = 30/x

60x = 6600
x = 110
C
EDIT: nevermind, JamieB is right, it's A. I need to read questions more carefully.

God I wish I was still in algebra

EDIT:

Actually, forget all that crap. Go with the elephant! It's bulletproof!

The last question is A.

The stopping distance is proportional to the square of the speed, so when speed halves, the stopping distance quarters.

I still need a legitimate answer for number 2. The possible answers are: A. 8x^3 + 12x^3 +18x B. 8x^3 - 18x C. 8x^3 +18 D. 8x^3 - 12x^2 +18x

Thanks for your help so far though.
The answer to 2 is 8x^3
