evablogger [386]

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 |
