Answer: Equation (y = 3x + 10)
Each time the number of triangles increase, the 3 also increases. For example: 2 Triangles = 3 + 3 and the 2 of the 5 remains the same no matter how many triangles there are.
Step-by-step explanation:
Let x = Number of triangles
Let y = Perimeter
Plug in formula: y = 3x + 10
y = 3 (2) + 10
y = 6 + 10
y = 16
