Answer:
[tex]\begin{pmatrix}7\\ 4\\ 2\end{pmatrix}[/tex]
Step-by-step explanation:
3x3 and 3x1. Dimension is 3x1
[tex]\begin{pmatrix}3&6&1\\ 2&4&0\\ 0&6&2\end{pmatrix}\begin{pmatrix}2\\ 0\\ 1\end{pmatrix}[/tex]
[tex]\begin{pmatrix}3\cdot \:2+6\cdot \:0+1\cdot \:1\\ 2\cdot \:2+4\cdot \:0+0\cdot \:1\\ 0\cdot \:2+6\cdot \:0+2\cdot \:1\end{pmatrix}[/tex]
[tex]\begin{pmatrix}7\\ 4\\ 2\end{pmatrix}[/tex]
