Respuesta :

[tex]2A = \left[\begin{array}{ccc}8&18\\26&10\end{array}\right][/tex]

Step-by-step explanation:

Given

[tex]A = \left[\begin{array}{ccc}4&9\\13&5\end{array}\right][/tex]

We have to find 2A which means all the elements of the matrix have to be multiplied by the integer 2

So,

[tex]2A = 2\left[\begin{array}{ccc}4&9\\13&5\end{array}\right]\\= \left[\begin{array}{ccc}2(4)&2(9)\\2(13)&2(5)\end{array}\right]\\=\left[\begin{array}{ccc}8&18\\26&10\end{array}\right][/tex]

Hence,

[tex]2A = \left[\begin{array}{ccc}8&18\\26&10\end{array}\right][/tex]
