The general form of an even number is 2n. So, odd number is 2n + 1 and 2n + 3.
Now, we have as the follows,
(2x + 1)(2x + 3) = 323
Or, 4x^2 + 6x + 2x + 3 = 323
Or, 4x^2 + 8x - 320 = 0
Or, x^2 + 2x - 80 = 0
Hence, the quadratic equation established is
That's it..
I would say it represents the volume function evaluated at r=5/7, or
V(5/7)=(4/3)π(5/7)² = 2.13714

Answer:
Step-by-step explanation:
Take the value for b, divide it by 2 and square it to get the value for c.
In this case, b = -10.
- 10 ÷ 2 = -5
-5^2 = 25
So x^2 - 10x +25 is your quadratic equation which is equal to
D = 4n - 2
+2 +2
d + 2 = 4n
Divide both sides by 4
n = d + 2 / 4
