For the third to last question - I got -3x-4 as (3-x)(-3x-4) expands to make the expression on the bottom of the fraction, and the (3-x) cancels out, leaving -3x-4.
I got that too but apparently it's 1/-3x-4 because when you cancel out the top it doesn't become 0, it becomes one (since anything divided by itself is 1)
I got £42.27, or something really close to that, because he needs £17.50 for parking for 5 days and I think he uses £24.77 worth of petrol in total and you add those two together to get the final cost.

I have just realised I forgot the parking and so would have been a lot more than I probably calculated.
