Flip the image.

Ok so you have to work backwards so lets say
x=50
work backwards does the answer you got make sense for it to be that answer
X × x = x^2
x × -3 = -3x
3 × x = 3x
3 × -3 = -9
x^2 + 3x - 3x - 9
So I would agree with C because the -3x and the 3x cancel each other out. I hope this helps!
Answer: That would be 15ft
