What the questions are asking help ASAP please

Answer:

Step-by-step explanation:

A scalar is a constant value that is multiplied throughout a matrix.

e.g.

In number 1 the set up would look like this

3 * $\left[\begin{array}{ccc}3&-1&5\\2&1&-4\\-6&3&2\end{array}\right]$

To solve this, you must distribute the 3 to each value within the matrix

The solution to #1 would be

M = $\left[\begin{array}{ccc}9&-3&15\\6&3&-12\\-18&9&6\end{array}\right]$
