Answer 2

d. 19

Explanation:

A matrix is an array of rectangular shape which consists of numbers, symbols, or expressions, arranged in rows and columns.

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

`w_(1,3)` means element in first row third column. First row means Frank and third column means August.

So, the number of lawns mowed by Frank in August is

`w_(1,3)=19`
