Oh no I copied it out from my workings wrong: 2r^2 + 1225/3468 r - (4742591/3668).
this is what I did http://www.thestudentroom.co.uk/atta...9&d=1463079399 could you point out any errors

Oh ignore me completely! I was looking at one of my earlier versions the worksheet. You're correct
3. Has anyone got a worked solution to question 15 please http://crashmaths.com/wp-content/upl...-Worksheet.pdf struggling to get my head around it! Thanks
4. Do you have the answer to the question?

No, unfortunately there's no mark scheme for these worksheets

I have tried to work through but not sure if I have the right answer

This question has added years on to me
so we know it is a parallelogram, therefore, i made some equations using these facts and modelling c as a=bi
OC=AB
OA=CB
OB^2+CA^2=2(OA^2+CB^2)

a^2 +b^2=160
84-5b=6a

i have put the equations in order in which i developed them from the facts

i used all these equations to get a is 4 and b is 12

sorry if my explanation is bad

Haha I know how you feel! Where did you get the 160 from, did you use a sketch at all? Struggling to visualise it!

yh but my phone is out of battery
(AB)^2=(OC)^2

(AB)^2= (6-2)^2 +(5--7)^2
(AB)^2= 4^2 + 12^2
(AB)^2=160

(OC)^2=(a-o)^2+(b-0)^2
(OC)^2=a^2+b^2

11. I drew a diagram and found the displacement of point B from A. Then I knew that point C will be displayed the same distance from the origin as it is the opposite side of BA so I was able to deduce the coordinate of C.

You got as well, didn't you? It just looks like your method was a little contrived.

soz i thought you put b is 13 , night brain is kicking in
18. Oh yh silly mistake again, you can see my idea though. My bad again, sorry.

Yeah, I could see it was just a silly typo, only corrected you because I didn't want anybody to get confused. Don't apologise!

I need to take my time when trying to help people, I'll review my answers before posting them now because as you said it might confuse people.
