Answer
$\left[\begin{array}{ll}
0 & -4\\
6 & 4\\
2 & -10
\end{array}\right]$
Work Step by Step
If $A$ is a matrix and $c$ is a scalar, then $cA$ is the matrix formed by multiplying each element in $A$ by $c$.
$2B=2\left[\begin{array}{ll}
0 & -2\\
3 & 2\\
1 & -5
\end{array}\right]=\left[\begin{array}{ll}
0 & -4\\
6 & 4\\
2 & -10
\end{array}\right]$
