Thats a link to something on a school server I think. You must upload the file to the internet.

Did you get

M=20*L^3

?

M = L^3. M=160. L = 2^3 which is 8. 160/8 = 20. Then times it by 3 which gets you 60!!!!!?

Trig one? Sin32 x 12 = 6.35

Can somebody please explain how you solve 3x + 7x - 13 = 0?

You have to use the quadratic equation which is given to you at the beginning of the paper and you just have to substitute the correct numbers into the equation (:

nah the one before about ticking three expressions that could represent area

anything that is squared has area in it or has a 2 I think :confused:

^ what did you get for the proportion question?

TheFootyKing19 - I followed exactly what you said, and I still can't seem to get it right. When you put your numbers back into the equation, they do not work (equal 0).

This part is right.

But you don't times this by three to get your answer - you need to cube 3 first because it is L cubed, not L.

3*3*3 = 27. 27*20 = 540.

The quadratic formula is

x = \dfrac{-b \pm \sqrt{b^2-4ac}}{2a}

. That is if you have a quadratic of the form

ax^2+bx+c=0

then you can calculate the two values of x using this forumla. I am almost certain that you are given this at the front of your exam paper and so that question is a really nice one to get provided you can use a calculator correctly.

Any other questions which anybody needs help with then do feel free to ask, I am more than happy to help. That goes for any GCSE maths question you need help with from any paper, provided you supply me the question :smile:

How do you do question 24?

As it's not trig, as there's no right angle (you can't make one as it's not isosceles).
You can't use a^2 = b^2 etc. as you don't want to find out a side;
And for the other one you need at least one angle.
