    D.

    Step-by-step explanation:

    Lets look at equation D:

    4 (x + 1) = 4x + 4

    4x + 4 = 4x + 4.

    The left side is identical to the right so

    you can put x equal to any number and this equation will be true.

    the answer is D

    Step-by-step explanation:

    the equation works with every number placed where the x is, for example:

    4 (5+1) = 4*5 + 4

    4*6=20+4

    24=24

    but it also works with

    4 (11+1) = 4*11 + 4

    4*12=44+4

    48=48

    and it also works with every possible number you can think!
