The following table shows the length and width of two rectangles: Length Width Rectangle A 2x + 4 x − 1 Rectangle B 3x + 1 2x −
3 Which expression is the result of the perimeter of rectangle B minus the perimeter of rectangle A? 4x − 10 4x − 14 16x + 18 16x + 14
1 answer:
Answer:
4x − 10
Step-by-step explanation:
The width of rectangle A is 2x+4 and the length of rectangle A is x-1. This makes the perimeter
2(2x+4)+2(x-1)
= 4x+8+2x-2
= 6x+6
The width of rectangle B is 3x+1 and the width of rectangle B is 2x-3. This makes the perimeter
2(3x+1)+2(2x-3)
= 6x+2+4x-6
= 10x-4
Subtracting Perimeter B - Perimeter A, we ahve
(10x-4)-(6x+6)
= 10x-4-6x-6
= 4x-10
