Answer:

- (\frac{15 - 4\sqrt{3} }{11} )

Step-by-step explanation:

\frac{\sqrt{3}-6}{\sqrt{3} +6} = \frac{(\sqrt{3}-6)(\sqrt{3}-6)}{(\sqrt{3} +6)(\sqrt{3} -6)}

= \frac{(\sqrt{3})^2 - (2\times6\times\sqrt{3}) +6^{2}   }{(\sqrt{3})^2 - 6^{2}}  = \frac{9 - 12\sqrt{3} + 36}{3 - 36}

\frac{45 -12\sqrt{3}  }{-33} =- (\frac{15 - 4\sqrt{3} }{11} )

How much longer does it take a automoblie to travel one mile at 20 miles per hour than at 30 miles per hour? show your work.
zalisa [80]

Answer:

A

Step-by-step explanation:

At the rate of 20 miles per hour, the car will travel 20 miles every 60 minutes, or a third of a mile every minute. This means that it will travel a mile in 3 minutes. For the car travelling at 30 miles per hour, it will travel half a mile every minute, or a mile every 2 minutes. 3-2=1 minute, or choice A. Hope this helps!
