put this solution on YOUR website!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.
Step 1. Let x be the length of the first side.
Step 2. Let 2x be the length of the second side since the second side of a triangle is twice the first side.
Step 3. Let 2x+10 be the length of the third side since the third side is 10 more than the second.
Step 2. Perimeter P is when you add the three sides of the triangle.
Step 3. Then
or
. Then
With x=12, then 2x=24 and 2x+10=34. Check Perimeter P=12+24+34=70 which is a true statement.
Step 4. ANSWER. The sides are 12, 24, and 34 feet.
I hope the above steps were helpful.

------------------------
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
