Question

The dimensions of a rectangular sandbox are 4x + 2 by 2x + 4. The dimensions of a rectangular garden are 3x - 2 by x + 4. Which

expression represents how much more area the sandbox covers than the garden?
O A 5x2 + 10x + 16
OB. 10x2 + 8
o C. 8x2 + 20x + 8
O D. 11x2 + 30x

Answer 1

A. 5x²+10x+16

Explanation:

Sandbox Dimensions - Garden Dimensions

(4x+2)(2x+4) - (3x-2)(x+4)

(8x²+20x+8) - (3x²+10x-8)

5x²+10x+16
