V = 4/3πr^3V = 4/3 (π) (6.5)^3
V = 366.1666π (6 repeat)
answer is 366.16 π (3rd choice)
Answer:
x = 1
Step-by-step explanation:
x 1
-------- = ----
x + 1 2
Begin the solution by multiplying both sides by the LCD, which is 2(x + 1):
2x = 2(x + 1)/2, or
2x = x + 1, or
x = 1
1
Check: is -------- = 1/2?
1 + 1
YES
Answer: The solutions are x=4 and x=-4
Step-by-step explanation: This is a quadratic equation, so we need to find when the equation equals 0. The values 4 or -4 both make it 0.
(if it is asking for you to factor it out, it is x^2 -16)
