One can solve this by first using order of operations, and then combining like terms.
First is parenthesis
9x + 2x(9) - 2(9x)
Now we do the multiplication
9x + 18x - 18x
Now we combine like terms
9x
20 it would be that alright
D. is definitely the right answer.
In set 0, all the numbers (2, 3, 5, 7) are all prime, and in between 0 and 10 (non-inclusive).
In set P, the condition is that x should be prime and in between 0 and 10 (non-inclusive).
As they're both the same, they can fit within one circle on the Venn diagram.
