For the trapezium question, where you had to prove the perimeter I messed up my trigonometry because I drew the special triangle wrong I ended up close to the answer 3(5 + root 3) will I get any marks?

That makes me feel better that other people made the same mistakes, I'm hoping for 2 out of 4 as well. I'm so annoyed at myself because I know I can do it

Are there any questions missing or is this all of them do you think?

The range answers were the integers: 9, 10, 11. As you found it was 0 when x was 8 or 12, therefore only smaller than 0 if 9,10,11

one answer was 121 (so root answer would be 11) which was one like (3-rootX)^1/3 = 2^3 or something

one surds question answer gave x = 45. As we were left with rootX = 3 root5 which is equal to root9 * root 5 = root 45 so x is 45.

For the range of x values question, I put 9, 10 , 11 because the question asked for integer solutions? I did put 8 < x < 12, but only in the working out

What would you say the minimum mark in this paper is if you wanted an A^? That's including silly mistakes and such

would I get marks if I put the integer values as 8, 9, 10, 11, 12?

for question 4 there was one where you had to circle the co-ordinates for the equation of a circle, which was (-5,8) and a second part to the question was to find the radius which I put as the square root of 10.
