If A=11-13,B=12-42,C=-7632 verify that A (B + C) = AB + AC.

If $A = (\begin{matrix} 1 & 1 \\ - 1 & 3 \end{matrix}), B = (\begin{matrix} 1 & 2 \\ - 4 & 2 \end{matrix}), C = (\begin{matrix} - 7 & 6 \\ 3 & 2 \end{matrix})$ verify that A (B + C) = AB + AC.

Match the items on the right to the items on the left.
