Question

ASAP HELP! MATRICES!

Answer 1

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

Step-by-step explanation:

Given

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

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

So,

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

Hence,

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