Ralph wants to build a rectangular deck with a predefined area of 594 feet squared. One side of the deck will be 93 feet longer than the other. To find the side lengths, he first writes the equation (x)(x +93) = 594 and later simplifies it to
(x - 6)(x +99) = 0, where 2 is the length of the shorter side.
Which of these are the side lengths, in feet of the rectangular deck? Select all that apply.
