Answer 1

`A=\left[\begin{array}{ccc}3&0\\2&-1\end{array}\right]\\\\B=\left[\begin{array}{ccc}2&8\\0.6&3\end{array}\right]\\\\A\cdot B=\left[\begin{array}{ccc}3&0\\2&-1\end{array}\right]\cdot\left[\begin{array}{ccc}2&8\\0.6&3\end{array}\right]=\left[\begin{array}{ccc}(3)(2)+(0)(0.6)&(3)(8)+(0)(3)\\(2)(2)+(-1)(0.6)&(2)(8)+(-1)(3)\end{array}\right]\\\\=\left[\begin{array}{ccc}6&24\\3.4&13\end{array}\right] \to\boxed{A.}`
