You haven't provided any value, but I can tell you the solution set for the inequality.
First of all, expand both sides:

Add 3x to both sides:

Add 6 to both sides:

Which is of course equivalent to

Divide both sides by 9

So, every number smaller than 2 is part of the solution of this inequality.
Answer:
the answer is c
Step-by-step explanation:
- The best method to test Zoe's claim is an observational study, as with this method it is possible to observe if the claim presents some truth to it. Observational studies are often used in testing claims like Zoe's as they allowed to have a great access to the variable that are behind a claim of that type, and so they are also more accessible.

I think it might be 20 I don't really know that one
