Answer 1

[24 -12 6]

7 3 0

Unless you also multiply the bottom, then it's:

[24 -12 6]

42 18 0

Explanation:

6 * 4 = 24

6 * -2 = -12

6 * 1 = 6

----------------

6 * 7 = 42

6 * 3 = 18

6 * 0 = 0

Answer 2

Explanation:

What you are being directed to do is multiply every element in the matrix by 6.

`6*\left[\begin{array}{ccc}4&-2&1\\7&3&0\\ \end{array}\right]`

`\left[\begin{array}{ccc}6*4&-2*6&1*6\\7*6&3*6&0*6\\ \end{array}\right]`

`\left[\begin{array}{ccc}24&-12&6\\42&18&0\\ \end{array}\right]`
