Answer:
The answer to your question is the letter C
Step-by-step explanation:
Data
When we multiply a scalar by a matrix, we must multiply the scalar by each of the numbers of the matrix and the result of the multiplication stays in the same place.
For this problem:
3 | -2 0 | = | (-2 x 3) (0 x 3) |
| 4 -7 | | (4 x 3) (-7 x 3) |
= | -6 0 |
| 12 -21 |
