Question 953943: One end of the glass prism is in the shape of a triangle with the height that is 1 inch longer than twice the base. If the area of the triangle is 39 square inches, then how long are the base and height?

base = b
height = 2b + 1
area = (b)(2b+1)/2 = 39
(b)(2b+1) = 78
2b^2 + b - 78 = 0
(b-6)(2b+13) = 0
Distance can't be negative, so the base is 6 inches and the height is 13 inches.
