The following table shows the length and width of two rectangles. (The table will be in comment section) Which expression is the result of the perimeter of rectangle B minus the perimeter of rectangle A?
A. 2x-4
B. 8x+10
C. 16x+20
D. 4x-8
Well what you need to do is find the perimeter of both rectangles. Rectangle A: ((2x+8)*2)+((x-1)*2)
Rectangle B: ((3x + 5)*2)+((2x-2)*2) That will be (10x+6)-(6x+14)=4x-8 Your answer will be D. Hope this is useful
