Step-by-step explanation:
There is nothing special in the given expression.
first of all we can arrange the likes terms together to reduce the expression, and there is no need of parenthesis so we can write
4a+4b+2b-c+5c
=4a+4b+4c
taking 4 common we get
4(a+b+c)
First we need to arrange the numbers in this number set from smallest to biggest:17,18,24,27,31,39,42,47,55,65. Then there are 10 numbers in this number set. So when we calculate the median, we need to find the middle two numbers and calculate their average. So the median is (31+39)/2=35. SO the answer is B

nearest thousandth
if the last 3 digits are over 500 then it's rounding up
