the length of a rectangular photograph is 8in. more than the width. if the area is 560 in^2 what are the dimensions of the photograph?

the width is______ in. and the length is _______ in.

help? thanks!

X in. = Width.

(X+8)in. = Length.

A = L * W. = (X+8) * X. = 560In^2.
x^2 + 8x = 560
x^2 + 8x - 560 = 0.
Use Quadratic Formula:
X = 20 In = Width.
X+8 = 28 in = Length.
