Question

Represent the above relationship between the number of triangles and the perimeter of the figures they form by filling in the table below. Show your work.

Answer 1

I'm not entirely sure the format you want the answer in but the table filled out is 

1 triangle/ perimeter of 17
2 triangles/ perimeter of 22
3 triangles/ perimeter of 27

The relationship is every time you add a triangle the perimeter goes up 5
So it's something like 

perimeter= 17+5(# of triangles)  

So if P=perimeter and T= # of additional triangles, the relationship would be

P= 17+5t

Answer 2

Answer would be P= 17+5t
Solution:

1 triangle/ perimeter of 172 triangles/ perimeter of 223 triangles/ perimeter of 27

perimeter= 17+5
So if P=perimeter
and T= # of additional triangles
SO the relation would be P= 17+5t.
