Question

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

A triangle is shown with side lengths labeled 2.3x plus 14, 2x, and negative 0.2x plus 15.

4.1x + 29
4.1x − 29
4.5x + 29
4.5x − 29

Answer 1

4.1x + 29

Explanation:

1. Combine like terms (2.3x + 2x= 4.3x - 0.2x = 4.1x)

2. add the 14 + 15 = 2

That gives you the equation 4.1x + 29

I also took the test so I know I it's right ;)
