Simplify the following expression: 2x − 6y + 3x2 + 7y − 14x. 3x2 + 12x + y 3x2 − 12x − y 3x2 − 12x + y 3x2 − 12x − 13y

To find range, you need to take the largest data value and subtract it by the smallest data value. So in this case to find the range for Set A you would take the largest number (60) and subtract it by the smallest number (20) to get 40, which is your range for Set A. For set B you would do 60 minus 10 to get 50, which is your range for Set B. Hope this helped!
