24

Answer 1

Given a matrix
`A` an element inside a matrix is denoted by
`A_(ij)` where
`i` is a number of a row and
`j` is a number of a column in which the element is in.

Your matrix is called
`W` and it equals to,

`W=\begin{bmatrix}28&21&19\\17&24&15\\22&29&17\\\end{bmatrix}`

So
`W_(11)` will denote the element in the first row and first column that is
`\boxed{W_(11)=28}`.

Hope this helps :)
