Question 7 A carpenter is making a backyard deck. In the measurements, he has determined that he needs to make a support triangle with an area 36m2. He knows that the base must be 1 less than 3 times the height. If the base is represented by 3x - 1 and height equals x. Find the equation that correctly shows the area of the triangle. 1 x(3x - 1) = 18 x(3x - 1) = 18 1 x(3x - 1) = 36 O x(3x- 1) 36
