Answer:
Its 9
Step-by-step explanation:
I did this in 5th grade... All you gotta do is count and there's 4 in the bottom aka 2 rows of 4 and there's 1 block on the top its 9
4+4+1=9
4+4=8
Add a 1 etc.
Do you have a question about it ?
This one is prime. The sum of two squares doesn't factor.
The more interesting case is q^2-1, which factors into (q-1)(q+1).
as a fraction the answer is
x=(10/9)
as a mixed number
x=1(1/9)
as a decimal
x=1.1
