Answer 2

A diferença entre as matrizes A e B é a matriz presente na alternativa D.

Explicação:

$A=\left(\begin{array}{ccc}-5&4&6\\3&6&7\\8&-1&-3\end{array}\right)$

$B=\left(\begin{array}{ccc}-4&5&-7\\-1&5&-6\\-2&-3&-1\end{array}\right)$

A diferença entre essas matrizes será:

$A-B=\left(\begin{array}{ccc}-5&4&6\\3&6&7\\8&-1&-3\end{array}\right)-\left(\begin{array}{ccc}-4&5&-7\\-1&5&-6\\-2&-3&-1\end{array}\right)\\\\\\A-B=\left(\begin{array}{ccc}-5-(-4)&4-5&6-(-7)\\3-(-1)&6-5&7-(-6)\\8-(-2)&-1-(-3)&-3-(-1)\end{array}\right)\\\\\\A-B=\left(\begin{array}{ccc}-5+4&4-5&6+7\\3+1&6-5&7+6\\8+2&-1+3&-3+1\end{array}\right)\\\\\\A-B=\left(\begin{array}{ccc}-1&1&13\\4&1&13\\10&2&-2\end{array}\right)$
