Question

Answer this for me plz.?

Answer 1

Step-by-step explanation:

Length = x-3

width = x+8

Area of the rectangle = 60 inch²

(x-3)(x+8)=60

x²+8x-3x-24=60

x²+5x-24=60

x²+5x-84=0

x²+12x-7x-84=0

x(x+12) - 7(x+ 12) =0

(x+12)(x-7)= 0

x= -12 or, x= 7

Measure of sides of rectangle can never be negative.

Answers:

Therefore,

x=7

Dimensions

length =7-3

=4 inches

width = 7+8

=15 inches
