Question

consider this matrix.
$a = \

$$\begin{bmatrix}-3 & -2 & 4\\\\12 & 8 & -4\\\\10 & -1 & 5\\end{bmatrix}$$

$
what matrix represents the expression $-3a$?
fill in the missing elements in the matrix.
$-3a = \

$$\begin{bmatrix} \\square & \\square & \\square\\\\ \\square & \\square & \\square\\\\ \\square & \\square & \\square\\end{bmatrix}$$

$

Explanation:

Step1: Multiply each element by -3

Multiply every entry of matrix $A$ by the scalar $-3$.

First row calculations:

$-3 \times (-3) = 9$, $-3 \times (-2) = 6$, $-3 \times 4 = -12$

Second row calculations:

$-3 \times 12 = -36$, $-3 \times 8 = -24$, $-3 \times (-4) = 12$

Third row calculations:

$-3 \times 10 = -30$, $-3 \times (-1) = 3$, $-3 \times 5 = -15$

Answer:

$$-3A =
