Question 992784
Dwayne's garden is triangle-shaped with two equal sides and a third side that is 4 ft more than the length of an equal side. If the perimeter is 49 ft, how long is each side? 
Which equation represents this? 
----
Sketch a picture of this isosceles triangle: equal sides are "x"; base = (x+4).
Equation:
x + x + x+4 = 49
3x = 45
x = 15 (length of each of the equal sides)
x+4 = 19 (length of the base)
