Also, you seem to be missing the 2 students who are supposed to be outside the 3 sets in question 21 a. There were 32 students and you have only listed 30.

no it was definitely -5+12 root 18. I got 2 at first but then realised I had it wrong

Yeah, and an easy way to check surds is to just put the first equation in your calculator, note the answer and then put your simplified equation in your calculator and if you get the same result it is right.

are u sure about q 19 it is -5+2 root 18 isnt it ????????
