Answer:

46m + 2mn

Step-by-step explanation:

Before we combine these like terms, let us simplify the exponent:

5m² = 5 × 5

5 × 5

= 25m

= 12m + 25m + 9m + 2mn

Now we can combine them. Only the bolded part should be added because the last value contains 'n" after the "m".

12m + 25m + 9m + 2mn

Add:

12m + 25m + 9m

= 37m + 9m

= 46m

46m + 2mn is our answer.
