I intially worked it out as OC and AB are parallel and OQB goes through both lines so I got two pairs of alternate angles. Where OQB and AC cross over you have vertically opposite angles. So you have two similar triangles. AP is the enlargened side of OC and AP is 1.5x OC so hence AQ is 1.5x QC so it is split 3:2. You wouldn't get much marks though as it is mostly not a vectro method.
Hi I hope you're doing well. For question 20 how do you know that you have to multiply 25 and 10^4n by 3/2? What I mean is why did you do that because I don't understand. Thanks a lot for your videos they really help.
I didn't multiply by 3/2. I raised them to the power of 3/2. The reason I did this is because the questions asked for a^3/2. So I had to raise both sides to the power of 3/2. Let me know if that makes sense.

Answer to question 10 should be 79.2, not 7.92. Sorry typo 😬.
Thank you so much. My teacher doesn’t explain things very well…
If 24 comes up in my exam I’m gonna cry 😭
I don’t even bother answering that far into the exam
That question comes up a lot
You should be worried abt 25

thanks a LOTTT it helps me a lot!
Hi, in 1:23:03 in q23 for the angle at C why is it 148”minus”x cuz isnt it like 180-(32”plus”x) to find that specific angle
148-x is the simplified form of (180 - (32 + x))
-> 180 - (32 + x)
-> 180 - 32 - x
-> 148 - x
hey in 56:38 shouldn't we cancel out the p squared by square rooting the whole thing?
Do you mean at the start of the question? No because that would put m in a square root and we need to get m on its own.
@@MrFlynnIB no i mean at the end there are two p squares at the end which we can cancel out by square rooting the whole thing
@@aznn00 No you definitely can't do that.
1:03:18 why didn't you minus 48 with 44.5 because that's what i did and got positive 3.5
It is 44.5 - 48. So negative 3.5.

@@MrFlynnIB I understand now and thanks so much for these videos!
Hi for Q22, can I just use the quadratic formula? Or do I need to factorise
Quadratic formula is fine.
Even the first question got me confused 😭
Excuse me, question 10 is incorrect, as I have observed the mark scheme and it clearly states that the answer is 79.2. Have a blissful day.
Shoot thanks you are correct.
@@MrFlynnIB No problem, thank you for all your videos they are saving me.
