Assignment 1 SQL Server Express Edition and AdventureWorksLT2012 answer to Unit 3 is not provided for Questions 4 and 10 which I need, and Question 9 code returns no results (assignment requires Join statements which I was able to use). Please advise. This is what I have:

use AdventureWorksLT2012
Select Customer.CustomerID, CompanyName 
from SalesLT.Customer, SalesLT.Address, SalesLT.CustomerAddress 
WHERE Customer. CustomerID= CustomerAddress. CustomerID 
AND CustomerAddress.AddressId= Address. AddressId 
AND Address.AddressLine1 Like '%United States %' OR Address.AddressLine2 Like '%United States %';
