The lengths of the sides of a triangle are 2a 3, a – 2, and 3a. Write a simplified expression for the perimeter of the triangle. Pls help

2a+3+a-2+3a

6a+1

Step-by-step explanation:

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

Step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137

answer: 5
