The area of a rectangle of length x is given by 3x^2 + 5x. Find the width of the rectangle.
The area of a rectangle is given by
(length) X (width) = Area ----(*)
Given length = x and area = 3x^2 + 5x
Therefore (*)becomes
(x) X (width) = 3x^2 + 5x
Therefore width = (3x^2 + 5x)/x = x(3x+5)/x = 3x+5
Answer: width = (3x+5)
Verification: Lenght = x and our width = (3x+5)
Therefore area = lenght X width = x X(3x+5) = 3x^2 + 5x which is correct.
