Answer 2

Step-by-step explanation:

Perimeter of triangle = Sum of 3 sides

Perimeter of triangle = a + b + c

Perimeter of triangle = (- 8x - 6y) + (9x + 13y) + (- x - 3y)

Perimeter of triangle = -8x - 6y + 9x + 13y - x - 3y

Perimeter of triangle = (-8x + 9x - x) + (-6y + 13y - 3y)

Perimeter of triangle = 0x + 4y

Perimeter of triangle = x + 4y
