I found it! It’s 48 degrees

Please see attached drawing which I have written my work (in colour). Despite spending 1h on it I still can’t understand how to find angle BAC.

So 7 parts is worth £76 more than 3 parts which means that 4 parts = £76 So 1 part = £19 Therefore Andreas gets £57, Isla gets £38 and Paulo gets £95. So Andreas has £57 - £48.50 = £8.50 left Is this correct please?

hallelujah

Is the answer - Square root of m/3p < x < + Square root of m/3p

Where are I going from from here x^2 < m/3p x < Square root of m/3p

I need to see the answer to understand where I can't go

Never mind, I give up.

That x < + sqrt 1 or x < - sqrt 1

What's the solution then, I am stuck.

It has two solutions

Are there two solutions plus (Square root of m/3p) and minus (Square root of m/3p)

Am I correct then when I write this? 3px^2 - m < 0 3px^2 < m x^2 < m/3p x < Square root of m/3p

Is this the right approach? 3px^2 - m < 0 3px^2 < m x^2 < m/3p x < Square root of m/3p Is this correct please?

dy/dx = 3px^2 - m Where do I go from here please?
