Resposta:

Letra B.

Explicação passo-a-passo:

$\left[\begin{array}{ccc}-1&4&5\\0&2&7\\1&-1&-2\end{array}\right] +\left[\begin{array}{ccc}3&5&2\\-1&5&3\\4&2&2\end{array}\right]=A+\left[\begin{array}{ccc}2&7&2\\8&-1&-3\\-1&9&5\end{array}\right]$

$\left[\begin{array}{ccc}2&9&7\\-1&7&10\\5&1&0\end{array}\right] -\left[\begin{array}{ccc}2&7&2\\8&-1&-3\\-1&9&5\end{array}\right] =A$

$\left[\begin{array}{ccc}0&2&5\\-9&8&13\\6&-8&-5\end{array}\right] =A$
