Answer:
Explanation:
<em>The dimensions of a matrix</em> is the number of rows × the number of columns of the matrix.
Your matrix is garbled. Thus, to help you I will work with an hypothetical matrix.
Assume the matrix:
That matrix has four colums and 3 rows.
For instance, the first colum is:
Thus, it has 4 columns.
And the second row is:
Thus, it has 3 rows.
Hence, the matrix is 3 × 4.
The first number is the number of rows and the second number is the number of columnns.
