  4. A & B are correct.

    In C, the (-) sign should be (+) because 12 minus 9 is positive 3.

    In D, combine the constants:
    8 + 6d - 12
    = 6d - 4

    In E, combine the terms with variables:
    30e + 18 - 8e
    = 22e + 18

    In F,
    15f + 10 - f - 5
    = 14f + 5

    hope this helps :3
