So we've done all these before, its just some I've forgotton how to do some, etc and woudl just like to see how to do one so that I can then practice with some similar ones. I'm not looking for answers, I'm looking for solutions on how to do these (with an answer at the end, etc). I might add some mroe Q's here as I find more quite simple aspects I fail to recall immediately.
Simplify 5 divide by X^2 + 2x
--- -------------
X - 2 x^2 - 4
Simplify 2m - n - m - 3n
--------- -----------
3 6
Solve simultaneously
4x - y = 9
3xy = -6
Find M in its simplest forn.
m = (√5 - √3)^2 + √60
Solvw (2X-1)(X+6) = 0
A copper sphere has a mass of 700g. Calculate the radius of the sphere given that 1cm^3 of copper has a mass of 8.95g.
Thanks for any help/tips, etc.
