    First I would simplify each side in order to determine the symbol.

    2 * 18 - 18? 2 * [28 - 3 (2 + 4) ] I will simplify the left side first. Multiply 2 and 18

    36 - 18? 2 * [28 - 3 (2+4) ]

    18? 2 * [28 - 3 (2 + 4) ] Now simplify the right side. Add 2 and 4

    18? 2 * [28 - 3 (6) ] Next multiply 3 and 6

    18? 2 * [28 - 18]

    18? 2 * 10

    18? 20

    18 < 20 Your answer is C because 18 is less than 20

    First find the value of the give expression

    2 (a + 6) Since a = 2, plug in 2 for a

    2 (2 + 6)

    2 (8) = 16

    A.) 2a + a² Plug in 2 for a

    2 (2) + (2) ²

    4 + 4 = 8

    B.) 4a + 8 Plug in 2 for a

    4 (2) + 8

    8 + 8 = 16

    Neither A or B have a value greater than the given expression
