Question

The length of a rectangle is 5 inches more than its width, x. The area of a rectangle can be represented by the equation x 2 + 5x = 300

Answer 1

Step-by-step explanation:

area of rectangle = x*(x+5) = x²+5x

x² + 5x = 300

x² + 5x - 300 = 0

x² + 20x - 15x - 300 = 0

x(x+20) - 15(x+20) = 0

(x-15) (x+20) = 0

x=15✓

So , the width of rectangle is 15 inches and the length is 20 inches.
