Quizplus · Accepted Answer

The product of a 1x3 matrix $A$ and a 3x1 matrix $B$ is a 1x1 matrix, calculated as $(-6*9) + (2*0) + (3*-3) = -54 - 9 = -63$.

Find the Product, AB, If Possible A=[−623],B=[90−3]A = \left[ \begin{array} { l l l } - 6 & 2 & 3 \end{array} \right] , B = \left[ \begin{array} { r } 9 \\ 0 \\ - 3 \end{array} \right]A=[−6​2​3​],B=​90−3​​

Find the Product, AB, If Possible $A = \left[ \begin{array} { l l l } - 6 & 2 & 3 \end{array} \right] , B = \left[ \begin{array} { r } 9 \\ 0 \\ - 3 \end{array} \right]$
