You didn't provide any answer choices so this is what I found...
The Great Pyramid of Giza<span> was </span>built<span> for the Fourth Dynasty Pharaoh Khufu (or Cheops), and was completed around 2560 BCE.
This is mathematics, I think you meant to put this in History, lol. I hope my answer helps. I'm not sure if it was the answer you were looking for though. :)</span>
C is the answer I think sorry if I’m incorrect
I think you have to like find the median and then you have to see if the mean is more
A.3x+5=65
-5 -5
subtract 5 from 5, subtract 5 from 65 to get 3x=60
B. 3x=60
divide 3x by 3,divide 60 by 3 to get x by itself
x=20
