Answer 1

`\huge\boxed{\sf \left[\begin{array}{ccc}-12&18&0\\-24&12&36\\36&-30&36\end{array}\right] }`

Explanation:

Given matrix:

`= 3 * 2 \left[\begin{array}{ccc}-2&3&0\\-4&2&6\\6&-5&6\end{array}\right] \\\\`

• Multiply 3 and 2

`= 6\left[\begin{array}{ccc}-2&3&0\\-4&2&6\\6&-5&6\end{array}\right]\\\\`

• Distribute 6 to all the terms in the matrix

`= \left[\begin{array}{ccc}-2 * 6&3 * 6& 0 * 6\\-4 * 6&2 * 6&6 * 6\\6 * 6&-5 * 6&6 * 6\end{array}\right]\\\\= \left[\begin{array}{ccc}-12&18&0\\-24&12&36\\36&-30&36\end{array}\right] \\\\\rule[225]{225}{2}`
