first draw a triangle and label each side with the information given... two sides are going to be just x because the have the same length... the other side is going to be (x+7).. the perimeter is the addition of the three sides...
the equation will look as follows:
+x%2Bx%2B%28x%2B7%29=67+ by simplifying we obtain +3x%2B7=67+ then
+3x=60+and+x+=20 so the length of the three sides areas follows:
20 20 and 27.
