Answer 1

$2B- {A}^{t} + 3C$

$\left[\begin{array}{c c c}0 \times 2 & - 1 \times 2 \\2 \times 2 & 5 \times 2 \\\end{array}\right] - \left[\begin{array}{c c c}2 & - 3 \\ 1 & 4 \\\end{array}\right] +\left[\begin{array}{c c c}3 \times 3 & 0 \times 3 \\6 \times 3 & 1 \times 3 \\\end{array}\right]$

$\left[\begin{array}{c c c}0 & - 2 \\4 & 10 \\\end{array}\right] -\left[\begin{array}{c c c}2 & - 3 \\1 & 4 \\\end{array}\right] +\left[\begin{array}{c c c}9 & 0 \\18 & 3 \\\end{array}\right]$

$\left[\begin{array}{c c c}0 - 2 & - 2 - ( - 3) \\4 - 1& 10 - 4 \\\end{array}\right] + \left[\begin{array}{c c c}9 & 0 \\18 & 3 \\\end{array}\right]$

$\left[\begin{array}{c c c} - 2 & 1 \\3 & 6 \\\end{array}\right] +\left[\begin{array}{c c c}9 & 0 \\18 & 3 \\\end{array}\right]$

$\left[\begin{array}{c c c} - 2 + 9 & 1 + 0 \\3 + 18 & 6 + 3 \\\end{array}\right]$

$\boxed{\left[\begin{array}{c c c}7 & 1 \\21 & 9 \\\end{array}\right]}$

Espero ter ajudado!
