    6.2+8.7+8.9x

    Step-by-step explanation:

    For expressions to be equivalent, they must simplify to the same lowest form. 8.9x+6.2+8.7 simplifies to 8.9x + 14.9.

    Each of the expressions below must simplify to 8.9x + 14.9 to be equivalent.

    9x+6+9 = 9x + 15 NO

    3.9+6.2+8.7x = 8.7x + 10.1 NO

    3.7+8.9+6.2 = 18.8 NO

    6.2+8.7+8.9 = 23.8 NO

    6.2+8.7+8.9x = 8.9x + 14.9 YES

    3.9+6.2x+8.7 = 6.2x + 12.6 NO

    3.9x+8.7+6.2 = 3.9x + 14.9 NO
