An equilateral triangle has sides that measure 5x+3 units and 7x-5 units. What is the perimeter of the triangle?
Answered by Reiny
the two given sides must be equal

7x - 5 = 5x + 3
2x = 8
x = 4
so one side is 5(4)+3 = 23

the perimeter is 3(23) or 69 units

Thank you so much. I got confused when it said equilateral and it gave me two different units.
