Question

Se A= $\left[\begin{array}{ccc}-1&0\\2&1\end{array}\right]$ e B= $\left[\begin{array}{ccc}4&2\\2&0\end{array}\right]$ então a matriz 2A+ $\frac{1}{2} B$

Answer 1

$Ola' \\ \\ 2A+ \frac{1}{2}B \\ \\ 2\begin{bmatrix}-1&0 \\ 2&1\end{bmatrix} + \frac{1}{2}\begin{bmatrix} 4&2 \\ 2&0\end{bmatrix} \\ \\ \\ \begin{bmatrix}-2&0 \\ 4&2\\ \end{bmatrix}+\begin{bmatrix}2&1 \\ 1&0\end{bmatrix} \\ \\ \\ \boxed{\begin{bmatrix}0&1 \\ 5&2\end{bmatrix}}\\ \\ \\ \mathbb{xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx}\\~~~~~~~~~~~~~~~~~~~~~~~~Espero~ter~ajudado!!$
