Question

The three sides of a triangle are n, 4n+2, and 2n+14. If the perimeter of the triangle is 86 feet, what is the length of each side?

Answer 1

n = 10

10, 42, 34

Explanation:

permiter = length of each of the sides

86 = n + (4n +2) + (2n + 14)

solve for n

n = 10

put n back in the original equations

n = 10

4(10) + 2 = 42

2(10) +14 = 34
