Answer:
-1 Degree C
Step-by-step explanation:
When its talking about average temperature, its talking about the mean. To calculate mean, you add all the numbers and divide it by how many numbers are there.
(-8) + (-1) + 2 + 4 + (-2) = -5
mean = -5/5
-1 degree C
12 times 5 is 60
12-10=2, so 2 times 6 is 12, divided by 2 is 6
The area is 66
Yes you can you would have to combine 8n plus 8n which is 16n and then bring it down to 16n-4n to the second power
