Grafisch und rechnerisch
\( P(-5 / 0) \quad \vec{a}=\left(\begin{array}{l}3 \\ -1\end{array}\right) \quad \vec{b}=\left(\begin{array}{l}3 \\ 4\end{array}\right) \quad \vec{c}=\left(\begin{array}{c}-2 \\ 8\end{array}\right) \)
ges a) \( Q=P+\vec{a}+\vec{b}-\vec{c} \)
b) \( \overrightarrow{P Q}, \overline{P Q}=|\overrightarrow{P Q}| \)
