1. Consider the matrices below. For each pair or triplet of distinct matrices for which a product can be formed, give the order of multiplication and the dimensions of the resulting matrix. Note that you need not perform the multiplication.\\ $A = \begin{pmatrix} 4 & 5 \\ 8 & 9 \\ 1 & 3 \end{pmatrix}$, $B = \begin{pmatrix} 2 & 4 & 3 & 7 \\ 8 & 6 & 9 & 1 \\ 1 & 4 & 3 & 2 \end{pmatrix}$, $C = \begin{pmatrix} 2 & 4 & 5 \\ 4 & 7 & 7 \end{pmatrix}$
