Write an expression for the perimeter of the polygon. Simplify the expression.

8x + 13

Step-by-step explanation:

The perimeter is the sum of the 5 sides of the polygon, that is

perimeter = x + 5 + 3x + x + x + 5 + 2x + 3 ← collect like terms

perimeter = 8x + 13

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
