Answer:
then the perimeter of polygon B will also be twice of perimeter of polygon A
Hey there!
“12x - 24 = 180”
ADD by 24 on BOTH SIDES
12 - 24 + 24 = 180 + 24
CANCEL out: -24 + 24 because that gives 0
KEEP: 180 + 24 = 204
New equation:
12x = 204
DIVIDE 12 on BOTH SIDES
12x / 12 = 204 / 12
CANCEL out: 12 / 12 because of that gives you 1
KEEP: 204 / 12 because that gives the value “x”
204 / 12 = x
204 / 12 = 17
x = 17 ☑️
Good luck on your assignment and enjoy your day!

Call the width of the rectangle x. Call the length of the rectangle x + 2. The area of the rectangle would be the length times the width. We know this is 15 square inches. Set up the equation and solve for x.
(x +2)x = 15
x2 + 2x = 15
x2 + 2x - 15 = 0
Factor the quadratic equation:
(x - 3)(x + 5) = 0
x = 3 or x = -5
Since length can't be negative, discard the answer -5.
If x = 3, then the width is 3 and the length is x + 2 or 5. 5 x 3 = 15 which equals the area.
