10. A triangle has side lengths of (2x - 1) units, (8x-4) units, and 5x units. Which expression
represents the perimeter of the triangle?
FX15r+ 5) units
11. (x - 4x + 5x) units
G. (10x - 10) units
J. (15x - 5) units
15xt

15x - 5units

Step-by-step explanation:

Perimeter of a triangle = addition of all sides of the triangle.

A triangle is a polygon with 3 sides.

Therefore if the sides of the triangle are 2x - 1) units, (8x-4) units, and 5x units

Perimeter = 2x - 1 + 8x -4 + 5x

Collect like terms

Perimeter = 2x + 8x + 5x -1 - 4

Perimeter = 15x - 5units
