Question 4174: I'm trying re-arrange an equation to the form D = .......
Where
F = (2 * H * D * ( D - L ))/(( H - D + L )*( H + D - L ))
and
H = (L^2)/(f * D)
I just keep tying myself up in knots while doing it :(
If it helps, for any given scenario, D and L are changeable 'constants' so f is the real variable.
I think the form is quadratic, hence posting it here.
Thanks!

Question 5249: How do you solve this problem? Its been a while since I've taken any math and I have to take the pre-test for college. I can't find any examples in the pre GED book to help me figure them out. Any help would be appreciated.
1) Which of the following expressions represents the product of 3 less than twice x and 2 more than the quantity 3 times x?
2) If x=-1 and y=2, what is the value of the expression 2x3 (the 3 is small and above the x) -3xy?
3) For all x, 12x2-40x-32=?

Question 5703: Solve for r: 4(r-2)= 2(r+8)
This is how I am trying to do it:
I isolated the variable r
I multiplied the the terms
left side first, then right side and got:
4r-8 = 2r+16
Then I isolate r by subtracting both sides by 2 and got:
2r-8 = r+16
Then I isolated r by adding both sides by 2
4r-8 = r+16
Then I isolate r by dividing both sides by 2
2r-8 = 1r+16
Ultimately I got 4
and I seemed to got lost in the equation, please help :(
