MATRIZ:

$\begin{bmatrix}a11&a12&a13\\\end{bmatrix}$

$\mathit{a11}\Rightarrow\textup{3}\times\textup{1}+\textup{2}\times\textup{1}\Rightarrow\textup{3+2}=\boxed{5}$

$\mathit{a12}\Rightarrow\textup{3}\times\textup{1}+\textup{2}\times\textup{2}\Rightarrow\textup{3+4}=\boxed{7}$

$\mathit{a13}\Rightarrow\textup{3}\times\textup{1}+\textup{2}\times\textup{3}\Rightarrow\textup{3+6}=\boxed{9}$

$\begin{bmatrix}5&7&9\\\end{bmatrix}$$\Leftarrow\textbf{Resposta}$
