Which equation relates the number of triangles in the figure (n) to the perimeter of the figure (p) a. p=10n+14 b. p=10n+7 c. p=7n+10 d. p=7n+20. the perimeter of the triangles are 27. 34. 41.

Option d is correct.

Equation : P=7n+20.

Explanation;

Given the perimeter of each figure is;

Perimeter of triangle is equal to the sum of all the sides of a triangle.

Perimeter of 1 triangle is 21

Perimeter of 2 triangle is 34 and

Perimeter of 3 triangle is 41

Let n be the number of figure and P be the perimeter of the figure;

the only equation which satisfy the given perimeter is;

Check:

for n =1 which means 1 triangle then;

for n = 2 , [ i.e 2 triangle]

and for n =3 [i.e, 3 triangles]

Therefore, the equation P =7n+20 relates the number of triangles in the figure(n) to the perimeter of the figure(P).

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p
