...how?
B and D, because x^2+4x+2x-x^2=6x, as 2x+4x=6x and x^2+-x^2=0

But isn't the upper bound of 4.50 correct to 2d.p 4.505? And the lower bound should be 4.495?

18. so as the angle at the centre is double the angle at the circumference this means that .

since ABCD is a quadrilateral with all vertices on the circumference of the circle and ABC is opposite angle to ADC.
If anyone wants me to go on I can I have the full solution but it takes ages to write here.
