ANSWER
![12 \sqrt{5}](https://tex.z-dn.net/?f=12%20%5Csqrt%7B5%7D%20)
EXPLANATION
The given expression is
![\sqrt{2} \times \sqrt{72} \times \sqrt{5}](https://tex.z-dn.net/?f=%20%5Csqrt%7B2%7D%20%20%5Ctimes%20%20%5Csqrt%7B72%7D%20%20%5Ctimes%20%20%5Csqrt%7B5%7D%20)
The middle radical contains a perfect square.

Note that:
![\sqrt{a} \times \sqrt{a} = a](https://tex.z-dn.net/?f=%20%5Csqrt%7Ba%7D%20%20%5Ctimes%20%20%5Csqrt%7Ba%7D%20%20%3D%20a)
![6\times 2 \sqrt{5} = 12 \sqrt{5}](https://tex.z-dn.net/?f=6%5Ctimes%202%20%5Csqrt%7B5%7D%20%20%3D%2012%20%5Csqrt%7B5%7D%20)
Answer:
D. -1/2
Step-by-step explanation:
When a line is perpendicular to another line the slope will be the exact opposite. For example line A = y = 3x + 5 the line perpendicular to it will be -1/3x.
So -1/2 is the slope of your perpendicular line.
