Answer: 2n-8
Explanation: 2(n-6)+4 you bring 2 into the parentheses so 2 x n is just 2n
then 2 x -6 = -12
New equation 2n-12 +4
Now you combine-12 and 4 which is -8
Finale equation: 2n-8
The old mean was 51 now the mean is 42.33... (round that to 42) 51 - 42 = 9
Square root of 16 because it equals to 4 which is a rational number
