Question

The second side of a triangular deck is 5 feet longer than the shortest side and a third side that is  5 feet shorter than twice the length of the shortest side. If the perimeter of the deck is  60 feet, what is the length of the three sides

triciaal · Answer

let the middle = x
longer = more so add = +
twice the length = multiply by 2  shorter means less so subtract 
perimeter is the sum of the lengths  all around the figure.
for a triangle 3 sides perimeter the side 1 + side 2 + side 3 = given 60
I like to sketch  it helps me to "see" better
