The factored form is (x - 8)(x + 2).
(x - 8)(x + 2)
x^2 + 2x - 8x - 16
x^2 - 6x - 16
U didn't mess up....
V = pi * r^2 * h....divide both sides by (pi)r^2
V / (pi)r^2 = h
I'm pretty sure that it is refereed to a "face"<span />
Clear out any fractions by Multiplying every term by the bottom parts.
Add or Subtract the same value from both sides.
Divide every term by the same nonzero value.
Combine Like Terms.
Factoring.
Expanding (the opposite of factoring) may also help.
It would take 20 hours since 8,000 times 5 is 40,000 so 4 times 5 is 20.
