document.write( "Question 29274: A real tricky one for me. The question reads...The lengths of the sides of a quadralateral are consecutive even integers. Twice the length of the shortest side plus the length of the longest side is 120 inches. Find the lengths of the four sides. I began with 2x + y =120 and I know that this is only to figure two of the sides. I'm unsure of where to begin from here. thanks for your help. \n" ); document.write( "
