 Question 500772: The area of a triangular sheet of paper is 18 square inches. One side of the triangle is 14 inches more than two times the length of the altitude to that side. Find the length of that side and the altitude to that side. I have looked at the examples on here and struggled even with their guidance as to where some of the numbers come from so far I have.. base=2a+14 Altitude=a area= 18 so.. 2a+14= 18... so 2a=4.. I'm just very lost. Then I got 2x^2+14x-36=0 but when I tried to solve for it nothing was divisible by -18 that would equal 7 after you take a 2 out of the above question..
