What is 12m + 5m^2 + 9m + 2mn
2 answers:
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.
Answer:
5m^2 + 21m + 2mn
Step-by-step explanation:
You can add the like terms, which are 12m and 9m, resulting in:
5m^2 + 21m + 2mn
You can't add anything else together so that is the final answer.
