Answer

24 -12 0 20

Work Step by Step

In order to multiply a matrix by a number, we multiply every number in the matrix by that number in order to create the new matrix. For instance, to figure out the new number in the upper left corner of the new matrix, we multiply the number in the upper left corner of the original matrix by the number that the whole matrix is being multiplied by. Thus, we obtain: 24 -12 0 20
