question 17 points 1

find \\(a + b\\).

\\a = \

$$\begin{bmatrix} 3 & 6 \\\\ 5 & 8 \\\\ -2 & 9 \\end{bmatrix}$$

\quad b = \

$$\begin{bmatrix} -6 & 1 \\\\ 0 & 9 \\\\ 8 & 3 \\end{bmatrix}$$

\\

• \\(\

$$\begin{bmatrix} -3 & 7 \\\\ 5 & 17 \\\\ 6 & 12 \\end{bmatrix}$$

\\)

• \\(\

$$\begin{bmatrix} 6 & 12 \\\\ 10 & 16 \\\\ -4 & 18 \\end{bmatrix}$$

\\)

Explanation:

Identify the given matrices

Using the Matrix Addition knowledge point

$$ A =
LATEXBLOCK0
, \quad B =
LATEXBLOCK1
$$

Add corresponding elements

Using the Matrix Addition knowledge point

$$ A + B =
LATEXBLOCK2
=
LATEXBLOCK3
$$

Answer:

• **(A) \(

$$\begin{bmatrix} -3 & 7 \\ 5 & 17 \\ 6 & 12 \end{bmatrix}$$

\) (Correct answer)**

• (B) \(

$$\begin{bmatrix} 6 & 12 \\ 10 & 16 \\ -4 & 18 \end{bmatrix}$$
