@FO6DC4 Actually, with your wording, maybe I will allow for this one

@FO6DC4 I need a full solution please ;)

@24HourMaths Tried to find a way to minimise the product of the parts, then realised you could basically nullify the middle two and create the smallest possible answer, which in turn happened to be the correct answer. X = -6 (-6 + 3)(-6 + 5)(-6 + 7)(-6 + 9) = -3 * -1 * 1 * 3 = 9

@MattBecker82 It's a great question

@24HourMaths s = t² r = s² = t⁴ AD² = AB² (t – s)² + (s – r)² = 2(s – r)² t – s = s – r t – t² = t² – t⁴ t⁴ – 2t² + t = 0 t(t – 1)(t² + t – 1) = 0 Solve for t in (0,1): t = (√5 – 1)/2 t² = (3 – √5)/2 t⁴ = (7 – 3√5)/2 t² – t⁴ = √5 – 2 AB² = 2(s – r)² = 2(t² – t⁴)² = 18 – 8√5

I'm stuck on this one. Find the area of the circle.

@FO6DC4 Strong processing skills :)

@24HourMaths Went through it more methodically, found 4 more. 1, 2, 5, 7 1, 3, 4, 5 1, 3, 4, 6 1, 3, 5, 6 I believe this is now every combination

@FO6DC4 I do not think that that is a complete solution set, but your answers are all correct.

@24HourMaths If I've understood the question correctly, then I think I have 4. 1, 2, 3, 7 1, 2, 4, 5 1, 2, 5, 8 1, 3, 4, 9 I don't believe there are any others

@grundbirn This is correct - there was a typo in the question... the first x shouldn't be there! then it is a smoother answer :)

@24HourMaths x=128^(8/15)

Back in the game... part 1. For my Y11 this morning.

Part 2... what do we think?
