Question

consider matrix a.
$a = \

$$\begin{bmatrix} 9 & 35 \\\\ -2 & 5 \\\\ 6 & -7 \\end{bmatrix}$$

$
type the correct answer in each box.
the order of matrix a is $\square \times \square$.
entry $a_{12}$ is the value $\square$ in matrix a.

Explanation:

Step1: Identify matrix dimensions

The order of a matrix is given by $\text{number of rows} \times \text{number of columns}$. Matrix $A$ has 3 rows and 2 columns.

Step2: Locate entry $a_{12}$

Entry $a_{ij}$ refers to the value in the $i$-th row and $j$-th column. For $a_{12}$, this is the value in the 1st row, 2nd column.

Answer:

The order of matrix $A$ is $3 \times 2$.
Entry $a_{12}$ is the value $35$ in matrix $A$.
