#3\timesm+9#

Explanation:

First, start with "The sum". That gets you thinking of "#a+b#". Then, you go on with "3 times m", that's gotta be a multiplication: #3 \times m#. Then, you get to "9". Thus, you see there are 2 separate terms, "9" and "3 times m", which have to be the "#a and b#" of the original sum.
Hence, we finally have #3\timesm+9#.
