I graphed it out and it seems that both A and C are correct. I would check them to make sure.
7.) 4x greater because 8*8=64 and 4*4=16 64/16=4
8.) 22 because 70-13-13=44/2=22
9.) 32 because the square root of 64 is 8 so each side is 8 square feet
10.) The rectangle is an 8 by 5 and the perimeter is 26
If you are looking for the answer to the question above you have to ask yourself what two numbers multiply to 30 and equal 17 when added up. We halve the perimeter to make this easier. So your answer is 15 and 2 because 15 *2=30. If the sides are 15 and 2 then, 15(2) +2(2)=34. There is your answer.
