    B 12 and 14 Correct Answer Incorrect Answer
    C 14 and 16 Correct Answer Incorrect Answer
    D 16 and 18 Correct Answer Incorrect Answer

    Solution

    Let the integers be x and x + 2. Then, x┬▓ + (x + 2)┬▓ = 340. x┬▓ + (x┬▓ + 4x + 4) = 340, 2x┬▓ + 4x - 336 = 0, x┬▓ + 2x - 168 = 0. Using the quadratic formula, x = 12. The integers are 10 and 12. Answer: b) 12 and 14.
