Question

Write an expression for the perimeter of the triangle shown below:

A triangle is shown with side lengths labeled 0.5x plus 9, 3x, and negative 3.4x minus 25.

6.9x − 16
6.9x + 16
0.1x − 16
0.1x + 16

Answer 1

perimeter means add all the sides together

0.5x + 9 + 3x + (-3.4x-25) = ?

Answer 2

First, solve parenthesis. So do:\[(-3x-25)\]
