Question 215491
the second side of a triangle is twice the first side, and the third side is 10 more than the second. the perimeter is 70 ft. find the sides of the triangle
------------------------
Let the 1st side be "x".
The 2nd side is "2x".
The 3rd side = "2x+10"
----------------------------
Equation:
x + 2x + 2x+10 = 70 feet
5x + 10 = 70
5x = 60
x = 12 
----------
1st = 12 feet
2nd = 24 feet
3rd = 34 feet
