Question

Zohar is using scissors to cut a rectangle with a length of 5x – 2 and a width of 3x + 1 out of a larger piece of paper. Which expression can be used to find the perimeter of the rectangle and what is the perimeter if x = 4?

(5x−2)+(3x+1); 31 centimeters
(5x−2)+(3x+1); 36 centimeters
2(5x−2)+2(3x+1); 62 centimeters
2(5x−2)+2(3x+1); 70 centimeters

Answer 1

ok so what is the formula for this problem

Answer 2

(5x-2) (3x+ 1)

Answer 3

Thanks You

Answer 4

Np

Answer 5

L = 5x – 2
W = 3x + 1

formula for the perimeter of a rectangle: 2L + 2W

plug in (5x – 2) for L and (3x + 1) for W into the the perimeter equation. now, since it asks for the perimeter at x = 4, plug in x = 4 and evaluate.
