Question

Write the equation that represents the relationship between n the number of triangles and p the perimeter of the figures formed.

Answer 1

1 triangle: 2*6 + 1*5

2 triangles: 2*6 + 2*5

3 triangles: 2*6 + 3*5

So for n triangles: p = 2*6 + n*5 = 12 + 5n

Answer 2

Answer: for n triangles: p = 2*6 + n*5 = 12 + 5n
