Answer 1

$\tt 3\sqrt{6}-10 \sqrt{2}\cdot \sqrt{3} =3\sqrt{6}-10 \sqrt{6}=\boxed{\tt -7\sqrt{6}}$

Answer 2

Answer:

This answer is A) $-7\sqrt{6}$

Step-by-step explanation:

Multiply -10$\sqrt{2}$ and $\sqrt{3}$ to get -10$\sqrt{6}$

Think about $\sqrt{6}$ as x so the equation is 3x - 10x

3x - 10x = -7x

Plug back in $\sqrt{6}$ to get -7$\sqrt{6}$
