<PRE><B>Question 1094010</B>
first rectangle:


L = 2x-3
W = 4x-5
P = 2L + 2W = (4x-6) + (8x-10) = 4x-6+8x-10 = (12x-16)


second rectangle:


L = x-1
W = 3x+2
P = 2L + 2W = (2x-2) + (6x+4) = 2x-2+6x+4 = (8x+2)


difference is:


(12x-16) - (8x+2) = 12x-16-8x-2 = 4x-18


that should be your answer.
