Answer: 30k-24m

Step-by-step explanation:

so 9(2k-3m), there is an invisible multipulaction sign between the 9 and the parenthesis which means you have to multiply everything in there. 18k-27m.

Then -9m+12m+12k. Its a plus because two minuses make a positive.

18k-27m-9m+12m+12k. Now you put like terms together.

18+12k=30k, -27m-9m+12m= -24m

30k-24m
