Answer 1

Boa tarde!

• Temos uma Matriz QUADRADA de ORDEM 2.

Matriz:

$\begin{bmatrix}a11&a12\\a21&a22\\\end{bmatrix}$

___________________________________________________

$\mathrm{a11}\Rightarrow\mathrm{7\times1-1}\Rightarrow\mathrm{7-1}=\boxed{\boxed{6}}$

$\mathrm{a12}\Rightarrow\mathrm{7\times1-2}\Rightarrow\mathrm{7-2}=\boxed{\boxed{5}}$

$\mathrm{a21}\Rightarrow\mathrm{7\times2-1}\Rightarrow\mathrm{14-1}=\boxed{\boxed{13}}$

$\mathrm{a22}\Rightarrow\mathrm{7\times2-2}\Rightarrow\mathrm{14-2}=\boxed{\boxed{12}}$

Matriz resposta:

$\begin{bmatrix}6&5\\13&12\\\end{bmatrix}$
