Answer
$3m+11$
Work Step by Step
We are given the polynomial $4-(2+3m)+6m+9$.
First, we can use the distributive property to multiply out the terms in parentheses.
$4-(2+3m)+6m+9=4+(-1\times2)+(-1\times3m)+6m+9=4-2-3m+6m+9$
Next, we can combine like terms.
$4-2-3m+6m+9=(-3+6)m+(4-2+9)=(3)m+(11)=3m+11$
