I can't see the complete picture, but I know the #2 is either C or D. You simply get one of the expressions and multiply it by 2 (because of its opposite side.)
And once you've done that for both expressions, add that together and you have your answer. Hope that helped.

1) You are basically factoring -4x - 24 by choosing the GCF of the two terms (-4x and -24). The GCF is -4. To figure out the terms inside of the parenthesis you need to divide both of the original terms (meaning -4x and -24) by 4. So -4x/-4 = x and -24 / -4 = 6. 
-4(x + 6) 

2) To find the perimeter of a rectangle we multiply the width and length each by 2 (P = 2W + 2L) 
Length = x + 13
Width = x 
P = 2(x) + 2(x + 13) 
P = 2x + 2x + 26
P = 4x + 26

15. In a similar figure the sides are proportional. So you have to say which ratio of sides is also proportional or which sides are equal to the fraction 44/35.2

it would be c because :
44/35.2 = 132/105.6

16. same thing with similar triangles. if the length of sides are similar then so is perimeter. So so we find the ratio of the side lengths. We we know sq is 6 and qt is 24. So st is 30. So so the line st and sq are matching and similar so we compare their lengths and get a ratio
sq * x = st
6 * x = 30
x = 5

So so the perimeter is 5 times more than small triangle so
5 * 20 = 100

17.similar side is 0.5 and 3.6 so ratio is 3.6/0.5. we know she is 1.8 talk so
1.8 * 3.6/0.5 = 12.96
