Answer:
A. 9x + 4
Step-by-step explanation:
Perimeter of a triangle = side A + side B + side C
Side A = 2.5x + 3
Side B = x + 6
Side C = 5.5x - 5
Perimeter of a triangle = side A + side B + side C
= (2.5x + 3) + (x + 6) + (5.5x - 5)
= 2.5x + 3 + x + 6 + 5.5x - 5
= 2.5x + x + 5.5x + 3 + 6 - 5
= 9x + 4
Perimeter of a triangle = 9x + 4
The correct answer is A. 9x + 4
