Answer:

Multiply each entry by 2!

Step-by-step explanation:

Multiplying a matrix by a constant means to multiply each entry by that constant.

According to that, 2A would be the result of each entry being multiplied by 2.

That is equal to [tex]$ 2A = \begin{pmatrix}2(4) & 2(9) \\2(13) & 2(5) \\\end{pmatrix}[/tex]

[tex]$ \implies 2A = \begin{pmatrix}8 & 18 \\26 & 10 \\\end{pmatrix}[/tex]

Hence, the answer.
