Question

An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 5 more than two times the length of the bottom of the triangle. The last side is 8 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle.

Answer 1

Explanation:

P = 4x + 24

Explanation:

Sides of the triangle:

bottom = x

side1 = 2x + 13

side2 = x + 11

Perimeter is the sum of side lengths:

P = x + 2x + 13 + x + 11 = 4x + 24
