$\large\sf{}5 \sqrt{2} + 9 \sqrt{2} \\ \large\sf{}\left(5 + 9\right) \sqrt{2} \\ {\large\boxed{\boxed{  { \large \sf 14 \sqrt{2} }}}}$

B)

$\large\sf{} - \sqrt{2} - 5 \sqrt{2} - 10 \sqrt{2} \\ \\ \large\sf{} - 1 \sqrt{2} - 5 \sqrt{2} - 10 \sqrt{2} \\ \\ \large\sf{}\left( - 1 - 5 - 10\right) \sqrt{2} \\ \\ {\large\boxed{\boxed{  { \large \sf - 16 \sqrt{2} }}}}$
