Questão de Matemática

Referência: CHOAE/2022 - CBMERJ - Q12

Considere as matrizes abaixo:

\[ A = \begin{bmatrix} 2 & 4 & \\ -3 & 0 &\\ 1 & 3 \end{bmatrix} \]

\[ B = \begin{bmatrix} 3 & -1 & \\-2 & 4 & \\5 & 2 \end{bmatrix} \]

\[ C = \begin{bmatrix} -4 & 1 & \\ 3 & -2 & \\1 & 0 \end{bmatrix} \]

Calcule:

\[ A + B - C \]

\[ C = \begin{bmatrix} 1 & 2 & \\ 8 & 2 & \\5 & 5 \end{bmatrix} \]

\[ C = \begin{bmatrix} 1 & 2 & \\ -8 & -2 & \\5 & 5 \end{bmatrix} \]

\[ C = \begin{bmatrix} 1 & 2 & \\ -2 & -2 & \\7 & 5 \end{bmatrix} \]

\[ C = \begin{bmatrix} -5 & 2 & \\ -8 & 2 & \\-5 & 1 \end{bmatrix} \]

\[ C = \begin{bmatrix} 9 & 2 & \\ -8 & 6 & \\5 & 5 \end{bmatrix} \]
