Answer:

The answer is A

\left[\begin{array}{ccc}48&0&6 \\4&-24&28\end{array}\right]

Step-by-step explanation:

If we have a matrix A = (aij) and a real number, the product of a real number is defined by a matrix, in which each matrix element is multiplied by the real number.

In this case we have the real number 4 and the matrix C

C=\left[\begin{array}{ccc}12&0&\frac{3}{2} \\1&-6&7\end{array}\right]

Now, we need to multiply 4 by every term in the matrix, so we'll have:

4*\left[\begin{array}{ccc}12&0&\frac{3}{2} \\1&-6&7\end{array}\right] \\\left[\begin{array}{ccc}12*4&0*4&\frac{3}{2}*4 \\1*4&-6*4&7*4\end{array}\right] \\\\\left[\begin{array}{ccc}48&0&\frac{12}{2} \\4&-24&28\end{array}\right]

Simplify 12/2 :

\left[\begin{array}{ccc}48&0&6 \\4&-24&28\end{array}\right]

The answer is A.
