Answer:
No Solutions
Step-by-step explanation:
First to complete the square, it will need to look something like
a^2+2ab+b^2
so in order to get that we can see that 4n^2+8n seems to be missing a piece.
a is the square root of 4n^2 which is 2n.
8n/2n=4
4/2=2
b=2
so now add 2 to both sides of the equation so now it's
4n^2+8n+4=-13
rewrite as (2n+2)^2=-13
Now you see a negative number as the result of a exponent.
A number squared will never be negative.
Therefore the answer is
No Solutions
To find the mean or the avg you add up all the numbers you have and then divide by how many numbers you added together in this case 5
so the mean is 22, hope this helped you!
Answer:
-1
Step-by-step explanation:
96=84-12r
