Answer 1

1.

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

2.

$\left[\begin{array}{cc}0-5+9&1-1+0\\3-1+2&4-3+1\/\end{array}\right]$      =    $\left[\begin{array}{cc}4&0\\4&2\\\end{array}\right]$

Determinante:

D = (4.2) - (0 . 4)

D = 8

3.

$\left[\begin{array}{cc}(2.5+1.1)&(2.1+1.3)\\(2.5+4.1)&(2.1+4.3)\\\end{array}\right]$       =     $\left[\begin{array}{cc}11&5\\14&14\\\end{array}\right]$
