Question

this is a trapezoid and i am trying to find x
75cm^2=4x^2-5x

Answer 1

Looks like you just have an equation to solve x for....well that's what I take out of it anyhow. So solve \[4x^2-5x-75=0\] for x.

Answer 2

ok here is what they gave me
bottom base is 3x-7 right side is 2x top base is x+2

Answer 3

I am tryin to find x which I plugged into the area equation
75cm^2=.5(2x(3x-7+x+2))
75cm^2=.5(6x^2-14x+2x^2+4x)
75cm^2=.5(8x^2-10x)
75cm^2=4x^2-5x
