Kaylee is building a rectangular enclosure with an area of 90 square yards. She wants the length of the enclosed area to be 6 yards longer than the width, x. To represent this, she writes the equation x 2 + 6x = 90. She then completes the square to help solve her equation for x. Which equation is equivalent to Kaylee’s equation after she completes the square
