Question

The perimeter of the triangular park shown on the right is 15x-6. What is the missing​ length?

(Simplify your​ answer.)

Answer 1

missing side: 9x -3

Step-by-step explanation:

length + width + height = perimeter

4x + 1 + 2x - 4 + height = 15x - 6

6x - 3 + height = 15x - 6

height = 15x - 6 - 6x + 3

height = 9x -3
