Answer 1

Resposta:

Explicação passo-a-passo:

Temos

$A=\left[\begin{array}{c}1&-1&7&2\end{array}\right]$

$B=\left[\begin{array}{c}-4&3&1&5\end{array}\right]$

Assim

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