Question

An equilateral triangle has a perimeter of 51x + 3. What is the length of each side of the triangle?

Answer 1

An equilateral triangle has 3 equivalent sides

Divide 51x + 3 by 3

(51x +3)/3 = 17x + 1

17x + 1 is the length of each side.

hope this helps

Answer 2

First subtract 3 from 51 which gives you 48, then divide 48 by 3 which gives you the answer of 16.
