write down a simplified expression for the perimeter of this triangle

Question

A scalene triangle, 1 side is 9x-7w, 2 side is 4x+6y and 3 side is 5y+5w. What is the perimete

Answer 1

The perimeter of a triangle is the measure of side 1 + measure of side 2 + measure of side 3.  To find the perimeter of the triangle, simply add these sides together.

(9x - 7w) + (4x + 6y) + (5y + 5w)

Remove the parenthesis

9x - 7w + 4x + 6y + 5y + 5w

Arrange the order so that like terms are together

9x + 4x +6y + 5y -7w + 5w

Combine like terms

13x + 11y - 2w
