Answer:
The mean absolute deviation = 3.5°F
Step-by-step explanation:
The sum of the given temperatures, ∑T, is found as follows;
∑T = 66°F + 57°F + 61°F + 65°F + 54°F + 62°F + 59°F + 56°F = 480°F
The number of days, n, over which the temperature was tracked = 8 days
Therefore, the mean, 
, of the data set = ∑T/n = 480°F/8 = 60°F
The mean absolute deviation is given by the following formula;
Therefore, we have;
66 - 60 = 
= 6
57 - 60 = 
= 3
61 - 60 = 
= 1
65 - 60 = 
= 5
54 - 60 = 
= 6
62 - 60 = 
= 2
59 - 60 = 
= 1
56 - 60 = 
= 4
The mean absolute deviation is therefore;
The mean absolute deviation = (6 + 3 + 1 + 5 + 6 + 2 + 1 + 4)/8 = 3.5°F.

2(x + y) + 3(x + y)
first distribute:
(multiply 2 into everything in the first parenthesis, and 3 into everything in the second)
2x + 2y + 3x + 3y
Second simplify (add all like terms (adding in this case) )
(2x + 3x) + (2y +3y)
5x + 5y
your answer is: 5x + 5y
hope this helps
