Im doing 3-unit maths and we've been given this assessment, most students have had time to go over it with their tutor. Please trust me when i say ive been incredibly busy over the last week, and my tutor couldnt see me this week, so basically im screwd. We have to PRESENT the solution to the question to the class TOMORROW and i just dont know how to answer it. and believe me, i am not cheating by asking for help with this, its more about the way you present the question, the teacher told us to go over it with our tutors (3-unit maths is extension maths, aka Hard). So please if somebody could go over this and explain how to solve it i will be forever in your debt.

The question is attached as an image, please excuse my hastily written paragraph, i hope you'll understand why im rushing.
