Answer 4

Do you know the rule for multiplications between matrices?

Answer 5

not really

Answer 6

Matrices can only be multiplied if the # of columns in the first matrix is the same value as the # of rows in the second matrix.

Answer 7

Setup:

\[Rows \times Columns\]

In order to multiple matrices, they would have to look like

\[1 \times a \]
\[a \times 4\]

Since the # of columns in the first matrix and the # of rows in the second matrix are the same, we can multiply them.
