    3a+6

    Step-by-step explanation:

    3a+6 = 24a+48 divided by 8 (there are 8 sides in an octagon)

    covert 24a + 48 inches into feet

    2a+4 feet = 18 feet

    subtract 4 from both sides

    2a = 14

    divided 2 from both sides

    a = 7

    covert 3a+6 inches into feet

    0.25a + 0,5

    0.25 (7) + 0.5

    = 2.25

    verify your answer

    2.25 x 8 = 18
