    scope :user_answers_with_questions, -> { joins(:questions) & Answer.user_answers }
end

You should use | instead of & if you want to merge. Also I think you don't need to do Answer.useranswers, just call useranswers. Scopes are class methods and you are calling a scope from another, so you should not have any kind of problem with that.
