No, you're wrong, although both are divisible by 25, doing so would change the actual value of the end answer. The final answer is 100-25 pi
lol what... you never heard of factorisation?

Does factorising still count as simplest form? I'm always unsure so I never do it and I left my answer as 100-25pi

That is the correct answer bc if you do that on the calculator it equals to 21.... and if you factorise it down to 25(4pi -1) you get like 289.... which is incorrect.

Because it doesn't factorise to that. It factorises to 25(4-pi)

5. For the reflection and rotation questions, will i get 1 mark each? becuase i reflected on of the shapes correctly but i placed it somewhere else, and i also rotated it correctly but placed somewhere else

Hmm, not sure, loking at past grade boundaries it lpooks like average for an a* is 166, which would be 83 on each paper, meh, not much of a difference though.
12. thats wrong it was 0.04
13. omg im so annoyed i put 3.14 instead of the pi sign and actually worked it out,do you think i will still get some marks? why did i not read the full question!!!!
14. oh god i failed Maths GCSE
15. Wouldn't the simplified version be 5(2-m) because it says expand and simplify, and 10-5m isn't the simplified version.
16. somebody NEEDS to make a foundation paper one
(Original post by LogicalFallacy)

I wrote 75pi over 4. But i showed my working clearly so dod uthink i would still get 2 marks out of 3 for the working out?
Yeah I would think so
19. Hi guys, I have managed to get 81 will I be in a chance to get an A*, people are saying I need to get 166, so another at least 85 marks. But what was the grade boundaries for 2015, it had apparently low grade boundaries like 158 according to last year pupils. Is that correct?
20. for question 12
100- 25π cm²
would it be alright if i wrote : 25(4-π )cm²
