6m + 2 - 4m =<br><br><br>help with this please ​

First combine like terms.
<em>we do 6m-4m which is 2m</em>
2m+2=?

Second we factor. We notice that both terms have 2.
2(m+1)

<em>by distributive law, the 2 is distributed to m and 1.

Dada a Matriz A= [1 -2 1 ][-3 1 4] [0 6 8] , escreva uma matriz B diferente de A, tal que detA =detB.
Mariulka [41]

Use o fato de que o determinante de qualquer matriz quadrada é o mesmo da sua transposta.

\mathbf A=\begin{bmatrix}1&-2&1\\-3&1&4\\0&6&8\end{bmatrix}

\mathbf B=\mathbf A^\top=\begin{bmatrix}1&-3&0\\-2&1&6\\1&4&8\end{bmatrix}
