Step-by-step explanation:
Answer:
-3a² - ab - 7ac - 2b² + 6bc + 4c²
Step-by-step explanation:
Step 1: Distribute
3a² + 3ab + 3ac - 2ab + 2b² -2bc
Step 2: Combine like terms
3a² + ab + 3ac + 2b² - 2bc
Step 3: Distribute again
-4ac + 4bc + 4c² - (3a² +ab + 3ac + 2b² -2bc)
Step 4: Combine like terms again
-3a² - ab - 7ac - 2b² + 6bc + 4c²
And you have your final answer.
Answer:

To find the mean absolute deviation of the data, start by finding the mean of the data set.
Find the sum of the data values, and divide the sum by the number of data values.
Find the absolute value of the difference between each data value and the mean: |data value – mean|.
Find the sum of the absolute values of the differences.
Divide the sum of the absolute values of the differences by the number of data values.
The last two are correct. Thank you for the correction, I couldn't tell what you were trying to tell me the first time! :-)
