I basiclly just need a little review and maybe some 1 to show me how to solve out the equation/and equation like it. here is an example:
2x+1 / x-1 + 1/ x+1 = ?
The Attempt at a Solution
Heres my calculations, and i did make it .247 before.
9x10^9 * 43.1 x10-9/.247^2 + 9x10^9 * 61.7 x10^-9/.247^2
is that correct?
comes out to be 6.4 x10^3 + 9.1 x 10^3 = 15500?
Then what? Do i divide by two?
Alright i have two problems i need help with

Alright I have a few problems here.
1). A bird is flying with a speed of 18 m/s over water when it accidentally drops a 2 kg fish. If the altitude of the bird is 5.40 meters and friction is disregarded, what is the speed of the fish when it hits the water?
My work: I don't know if I did this...
