Ineed with #57. i got wrong answer and don't know what i did wrong

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
