Answer: The expression for the perimeter of the triangle is 9x -4

Step-by-step explanation:

Add the three given lengths.

(2x +1) + (3x) + (4x -5)

2x + 3x + 4x +1 -5

Combine like terms

9x - 4

That expression is the perimeter.

If we are given more information, it might be possible to solve for the value of x, and get a number, but the is as much as we can do here.
