How did you get 1.7 and 4.7. I drew the graph of x+y=6 so (y=6-x) and I wrote down the points of intersection

which are -1.7 and 4.7 scrub

For the x+y=6 simultaneous equation, you had to also give y coordinates as well as x coordinates so one should have 4 answers in total (x= .... y= ..... OR x=...... y= ......)

For the last question, could u simplify it to (1-root2) divided by 4, rather than (3-root6) divided by 12?? Cuz I simplified it

No, that's not how surds work. You can't simplify root six because no square numbers can come out of it.

Hi guys, for the last question about the triangles, I think i forgot to half the area for one of the triangles. Foolish me, so now i got the same answer as everyone else except at the bottom I have 6 instead of 12. Can I still get around 2 marks for that?

Hey, if anybody is willing...

You may want to edit the image for the last question so as not to mislead people.

AD = AB is not right.
