    since this is a rectangle, we know the diagnols bisect each other. i.e., 5x-7 = 2x -1 solve for x here and to get the length of the diagnol, plug x into 2(2x-1). and that will be your answer.

    5x-7 = 2x -1 subtract 2x from both sides 5x - 2x - 7 = 2x - 2x - 1 3x - 7 = -1 add 7 to both sides 3x - 7 + 7 = -1 + 7 3x = 6 x = 2
