( 7 +x)(8 + x) = 58

ehere x is the thickness of the frame

Answer 12

*facepalms* I forgot. Here are the answer choices
x^2 + 15x - 2 = 0
x^2 + 15x + 58 = 0
4x^2 + 30x - 2 = 0
4x^2 + 30x + 58 = 0

Answer 13

x^2 + 15x + 56 - 58 = 0

Answer 14

do you see which one it is now?

Answer 15

X^2+15x-2?

yes
