Question 571282: i need help finding the equation used to find the problem.
each of the two equal sides is 4 feet shorter than the third side. If the perimeter is 25 feet, find the lengths of the sides.
You can put this solution on YOUR website! Hello,
Let's have x-4 represent the two equal sides and x be the third side.
(x-4)+(x-4)+x=25
Combine like terms:
3x-8=25
Add 8 to both sides and divide by 3 to get:
x=11
Now we know the two equal sides are 7 feet and the other side is 11 feet.
