Two sides of a triangle are equal in length, and the third side is 5 less than the length of the equal sides. If the perimeter of the triangle is 49, how long are it's sides?

let the length of each of the 2 equal sides= n

then n+n+(n-5)=49

3n=44

n=44/3

let the length of each of the 2 equal sides= n

then n+n+(n-5)=49

3n=44

n=44/3

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
