Answer:
Once a month, the female releases an ovum (one egg) or sometimes two (ova). If an ovum has been released, and the couple have sex, a sperm can unite with it, fertilise it and make the first cell of a new baby. Once one sperm has fertilised the ovum, no other sperm can get in. For the sperm it's like a race and there is only one winner.

Answer:
x=35
Step-by-step explanation:
Since a quadrilateral's interior angles add up to 360°, we get this:
360-85-20=360-4x+x
340-85=360-3x
255=360-3x
-105= -3x
<em>Multiply both sides by -1</em>
105=3x
3x=105
<em>Divide both sides by 3</em>
x=35
The answer is (x^2-2)(x^2-3)
The correct answer is C.105
