Question

A rectangle has the width x and its length is 10 inches greater than the width. For what values of x are the area of the rectangle greater or equal to 24 square inches?

Answer 1

x(x+10) = 24

x^2 + 10x - 24 = 0

( x + 12)(x - 2 ) =0

x+12 results in negative measures

x-2 = 0

x=2

width must be 2 or more
