question 9 points 1

find \\(4c\\) if \\(c = \

$$\begin{bmatrix} 3 & 4 & 5 \\\\ 6 & 5 & 4 \\end{bmatrix}$$

\\).

\\(\bigcirc \

$$\begin{bmatrix} 12 & 16 & 20 \\\\ 24 & 20 & 16 \\end{bmatrix}$$

\\)

\\(\bigcirc \

$$\begin{bmatrix} 3 & 4 & 5 \\\\ 6 & 5 & 4 \\end{bmatrix}$$

\\)

Explanation:

Identify the given matrix and scalar

Using the Scalar Multiplication knowledge point

$$ C =
LATEXBLOCK0
, \quad k = 4 $$

Multiply each element by the scalar

Using the Scalar Multiplication knowledge point

$$ 4C =
LATEXBLOCK1
=
LATEXBLOCK2
$$

Answer:

• **\(

$$\begin{bmatrix} 12 & 16 & 20 \\ 24 & 20 & 16 \end{bmatrix}$$

\) (Correct answer)**

• \(

$$\begin{bmatrix} 3 & 4 & 5 \\ 6 & 5 & 4 \end{bmatrix}$$
