Question

What is the dimension of the matrix `[(10,-6,18,0), (-7,5,2,4), (3, 11,9,7)]`?

Answer 1

`color(green)(3xx4`

Explanation:

The dimension of a matrix is the matrix represented in the form of the number of `"rows"xx"columns"` in the matrix

`color(blue)([(10,-6,18,0),(-7,5,2,4),(3,11,9,7)]`

In the above matrix, there are `3` rows and `4` columns

So,the dimension of the matrix is `color(green)(3xx4`

Hope this helps! :)
