Answer:
The answer to your question is P = 6z - 5
Step-by-step explanation:
Data
One side = x
Second side = y
Third side = z
Perimeter of a triangle = One side + second side + third side
Process
1.- Write equations for each side
x = 4z + 3
y = z - 8
2.- Write the equation of the perimeter
Perimeter of the triangle = x + y + z
-Write the perimeter in terms of z
Perimeter of the triangle = (4z + 3) + (z - 8) + z
-Simplify
Perimeter of the triangle = 4z + 3 + z - 8 + z
= 6z - 5
