A RECTANGLE HAS SIDES OF x + 2 and x-1. what value of x gives an area of 108

Answer 1

(x+2)(x+1) = x^2 +3x +2 = 108

x^2 +3x - 106 = 0

factor or use the quadratic formula or graph and find the x intercepts

x= about 8.9 and -11.9

x+1 = about 9.9

x+2 = about 10.9

9.9 times 10.9 = about 107.9 = about 108
