<h3>What is a matrix?</h3>
Matrix is defined as the arrangement of the numbers variables and expressions in the table as rows and columns. A matrix, which is used to represent a mathematical object or an attribute of one, is a rectangular array or table containing numbers, symbols, or expressions that are organized in rows and columns.
To find the number of roads directly connecting the town J to the other towns find the determinant of the matrix.
The matrix will be solved as below:-
The determinant of the matrix will be calculated as below:-
D = 0(0 - 1 ) -2(0 - 3 ) +3(2-1)
D = 6 + 6
D = 12
Therefore, the number of roads directly connecting the town J to the other towns will be 12.
