The correct answer is 9x-3.

Perimeter is all of the sides added together. Add by combining like terms (all terms that are constant and all terms with an x)

Answer:

Perimeter = 9x - 3

Explanation:

Perimeter of a triangle is the sum of length of the three sides

Therefore in this case

Perimeter of this triangle = 4x -2 + 3x - 1 + 2x

perimeter = 4x + 3x + 2x - 2- 1

Perimeter = 9x - 3
