suppose:

|a b c|

|A| = |d e f | = 6

|g h i |

find the determinants of these matrices:

a)

|a c b |

B = |d f e |

|g i h |

b)2A

c) A^-1 (inverse of A)

Is there a way to find a number value for the determinants of these matrices only knowing that |A| = 6 ?

I know how to find a determinant, but this question is confusing to me since there are no values
