Advanced Math practice question

Answer: 3

Width = area ÷ length = 2x²/(6x) = x/3. At x = 9, the width is 3. (Check: 2 × 81 ÷ 54 = 3.)

Common wrong answers

If you answered 27

27 is 2x²/6 at x = 9 without dividing by the x in the length.

If you answered 54

54 is the length (6 × 9).

If you answered 162

162 is the area (2 × 81), not the width.
