Answer:
C
Step-by-step explanation:
To multiply matrices, the number of columns in the first matrix must equal the number of rows in the second matrix.
Matrix A has 2 columns.
Matrix B has 2 rows.
So the matrices can be multiplied.
Matrix A has 2 rows. Matrix B has 1 column. So the result will also have 2 rows and 1 column.
The first row is (5)(2) + (2)(3) = 16.
The second row is (3)(2) + (-1)(3) = 3.
