The shortest side of an isosceles triangle is labeled, in inches, in the triangle below. The two longer sides are 6 inches longer than the shortest side. The perimeter of the triangle is 33 inches.

Picture shows an isosceles triangle with 2x-3 under it

What is the length of each of the longer sides of the triangle?

Answered by oobleck
you know that the perimeter is the sum of all the sides, right? So now you have
each long side is 6 more than 2x-3 or 2x+3
2x-3 + 2x+3 + 2x+3 = 33
6x+3 = 33
6x=30
x = 5
So, each long side is 2(5)+3 = 13
Check: 7+13+13 = 33
