9m + p + 12p + 4m + 3p
To simplify the expression, we can combine like terms:
9m + p + 12p + 4m + 3p
Combining the m terms, we have:
(9m + 4m) + p + 12p + 3p
Simplifying the m terms gives:
13m + p + 12p + 3p
Combining the p terms, we have:
13m + (1 + 12 + 3)p
Adding the p terms gives:
13m + 16p
Thus, the simplified expression is 13m + 16p.
