-The product of the matrices is obtained by multiplying the correspond values and summing up;

pq=\left[\begin{array}{ccc}3\\2\\-1\end{array}\right] \times\left[\begin{array}{ccc}5\\-1\\2\end{array}\right] \\\\\\\\=(3\times 5)+(2\times -1)+(-1\times 2)\\\\=15+-2+-2\\\\=11

Simplify the expression. Explain each step:<br> 1. 3.5 + (x + 2.7)<br> 2. (8 x k) x 4
barxatty [35]
In a way, you are adding like terms.
3.5 + 2.7 = 6.2, therefore making the answer 6.2 + x

The brackets can be ignored so you are really just asked 8 x 4 x k. 8 x 4 =32 so you end up with 32k
