Answer: 
-2 (6x - y) = -12x + 2y
Step-by-step explanation:
By using the distributive property, you start by multiplying -2 and 6x which gets you -12x. You then multiply -2 and -y (in other words -y = -1y) so, -2* -y would get you 2 as a negative multiplied by a negative is a positive. So, adding them together would get your final answer: -2 (6x - y) = -12x + 2y
 
        
             
        
        
        
20, 25, 30, 30, 31, 40, 41, 49
median = 30.5
lower IQR = 27.5
upper IQR = 40.5
Range IQR = 40.5 - 27.5 = 13
answer is 13
