A scalar and matrix multiplication problem

pentagon [3]

Answer:

$\left[\begin{array}{ccc}-32\\4\\20\\-36\end{array}\right]$

Step-by-step explanation:

The product of a scalar times the matrix involves the product of that scalar times each of the elements of the matrix, resulting on the multiplication by "-4" of each of the four elements as shown below. These new product values end up being the new matrix elements.

$-4*\left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right] = \left[\begin{array}{ccc}-32\\4\\20\\-36\end{array}\right]$
