The 13th amendment because This amendment abolished slavery and involuntary servitude. For what’s happening now I think we need this amendment added to the constitution right now because a lot of people are dying for their race. Not only that but they also get accused of things that aren’t even they don’t know what happened. And it’s really sad because some people get plastic surgery because of their skin. For example Michael Jackson.

Answer:
B. 10 units
Step-by-step explanation:
The distance formula is useful.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((3-(-5))² +(-2-4)²) = √(64 +36) = √100
d = 10
The distance from L to M is 10 units.
Answer: ![\frac{\sqrt[4]{10xy^3}}{2y}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B4%5D%7B10xy%5E3%7D%7D%7B2y%7D)
where y is positive.
The 2y in the denominator is not inside the fourth root

The idea is to get something of the form
in the denominator. In this case, 
To be able to reach the
, your teacher gave the hint to multiply top and bottom by
For more examples, search out "rationalizing the denominator".
Keep in mind that
only works if y isn't negative.
If y could be negative, then we'd have to say
. The absolute value bars ensure the result is never negative.
Furthermore, to avoid dividing by zero, we can't have y = 0. So all of this works as long as y > 0.
