Answer:
3 a²b
Step-by-step explanation:
This is what I did:
3 a²b ( 5b² - 7a²)
when you try to expand this, it will give you back the original expansion so 3a²b is the greatest common factor

Mean absolute deviation: The average distance from each number in the set to the mean of the set.
Mean of the set:

9.6-3=6.6
9.6-8=1.6
10-9.6=0.4
12-9.6=11.4
15-9.6=5.4
Mean of 6.6, 1.6, 0.4, 11.4, and 5.4:
Answer: 
Step-by-step explanation:
For balancing a hanger,
The weight of both sides of the hanger must be equal,
Here, the left side weight = 24 unit,
While the right sides total weight = c + c + c + c + c + c
= 6 c
For balancing it,

⇒ 
Thus, in the balancing equation the value of c will be 4.
