I will do one question. Next time, place one question per post. This allows many tutors to reply. Everyone has a different method. The more people that reply, the higher your chances of finding or learning a method that is best for you.
To solve part a, simply replace x with 5 and simplify the function.
A(5) = (5)^2 + 5(5) + 6
A(5) = 25 + 25 + 6
A(5) = 50 + 6
A(5) = 56
