Answer
$6m+15n+30$
Work Step by Step
$\bf{\text{Solution Outline:}}$
Use the Distributive Property to find the product of the given expression, $
3(2m+5n+10)
.$
$\bf{\text{Solution Details:}}$
Using the Distributive Property which is given by $a(b+c)=ab+ac,$ the expression above is equivalent to
\begin{array}{l}\require{cancel}
3(2m+5n+10)
\\\\=
3(2m)+3(5n)+3(10)
\\\\=
6m+15n+30
.\end{array}
