Question 57965: A rectangular painting with a width of x centimeters has an area of x^2+50x square centimeters. Find a binomial that represents the length. I don't know where to begin here! I understand that the area (a) = x^2+50x, and that for solving for length and width for a rectangle we use a = l + w. From there, I am lost.

A rectangular painting with a width of x centimeters has an area of x^2+50x square centimeters. Find a binomial that represents the length.
:
We know area = L*W: x^2 + 50x = the area. and tells us the width = x. Find
length by dividing (x^2 + 50x) by the width which is given as x
:
%28x%5E2+-50x%29%2Fx = (x + 50) is the length
