The answer is the last one, 8 square root 6 because when factoring out 486 you will get 9 square root 6. When factoring out 24, you will get 2 square root 6 and the 6 is already factored out. After that you add and subtract and you will get the last answer 8 square root 6. Hope that helped.
There must be more students in the class, and most of the class must have scored lower then Paul and his friends. I could be wrong, but I hope this helps! :D
Yeah because he was at least 80% and when you add the grain and carbon that was total. Then divide the carbon. It will be 80%
Someone else asked the same question and got something written out for them. on another site, I found out that the first one was <span>: 8(14.13)=113.04</span>
