.
If you expand the determinant of the second matrix into the long formula in accordance
with the definition of the determinant, you will see that each term of this
decomposition is (-6) times the corresponding term of the expansion of the original matrix.
Therefore, the determinant of the second matrix is (-6) times the determinant of the original matrix.
ANSWER. The determinant of the second matrix is (-6)*5 = -30.
