Question

Which of the following matrix addition problems are possible?

Answer 1

Answer:

Option A

Step-by-step explanation:

When adding two matrices, they should be of the same sizes.

Option A:

Matrix $\left[\begin{array}{c}2&3\end{array}\right]$ has 2 rows and 1 column.

Matrix $\left[\begin{array}{c}3&4\end{array}\right]$ has 2 rows and 1 column too.

So, these matrices can be added.

The result will be

$\left[\begin{array}{c}2+3&3+4\end{array}\right]=\left[\begin{array}{c}5&7\end{array}\right]$
