    Well ...

    A.

    8 (2r) & 10r

    This is incorrect because the second option would be if you added 8r to 2r, not multiplied 8 to 2r.

    B.

    6r + 3 & 9r

    This is incorrect because you cannot add the 3 to 6r, because they are different.

    C.

    9 (3r-4) & 27r - 36

    This is correct because the two options are equivalent.

    D.

    r+r+r+r+r & r^5

    This is incorrect because the first part would need to be r x r x r x r x r for it to be true.
