Answer:
6x + 8
Step-by-step explanation:
The perimeter of the rectangle
P = 2(L + W)
Plug in
= 2(2x + 3 + x + 1)
= 2(3x + 4)
Distributive property
= 6x + 8
The perimeter of the rectangle = 6x + 8
Look at the attachment
y= 1/2x+2
y int is 2
x int is -2
plug in 0 for y int
set the equation equal to 0 for x int
