Write an expression in simplest form that represents the perimeter of the polygon

Perimeter = (11x + 12)

Step-by-step explanation:

Since, perimeter of a polygon is represented by the sum of measures of all sides,

Perimeter of the given polygon = 3x + (x + 10) + 5x + (2x + 2)

By adding like terms of the expression,

Perimeter of the polygon = (3x + x + 5x + 2x) + (10 + 2)

                                          = (11x + 12)

Therefore, expression for the perimeter is (11x + 12).

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
