24x^2+8x

We know that (8/27)^(1/3). = (2/3)Then do (2/3)^2 = (4/9)Split up 2/3, into powers of 1/3, and 2.

dy/dt = 4t dx/dt = 9t^2dy/dx = dy/dt * dt/dx= 4/(9t)

Using SUVAT-s = ut + 1/2 at^2Subbing in... 0 = 2t - 5t^2t = 5/2 = 2.5

To solve this problem, we want to make either the x or the y values either equation the same.To work out whether to change the x or the y values, work out the lowest common multiple for each.For x, the va...
