Pi is 3.14
1st # is 3.13
2nd # is 3.15
These numbers are irrational because pi=infinity
( I am not exactly sure if this is right so don't blame me if you get this wrong, I just tried to help.....) :T
The numbers are 1 and 2
1 squared = 1 because 1 x 1 = 1
2 squared = 4 because 2 x 2 = 4
4 - 1 = 3
Answer:
9
Step-by-step explanation:
18÷9=2
27÷9=3
54÷9=6
(2x^2-x-6)/x^2-4
Factor top and bottom and you get
(2x+3)(x-2)/(x+2)(x-2)
The (x-2) cancel out each other leaving,
(2x+3)/x+2
The domain is all real numbers EXCEPT for -2. The domain can never be -2 as it would to the bottom having a zero, and that can't happen
