lana66690 [7]

Answer:

Eggs are developed and released by the <em>ovaries.</em>

Sperm is produced by the <em>testes</em>.

Explanation:

Ovaries are the site in females where the production of egg takes place. After the formation of an egg, the egg is transported to the fallopian tube, where it might undergo fertilization if a sperm unites with it.

The sperm and the egg unite to form a fertilized zygote.

The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angle
Nadya [2.5K]

Answer:

2(8x^2-13x+10)

Explanation:

There are 5 angle s in a pentagon and we are assuming are pentagon is a regular one so the angles are all congruent.

Let's let A represent the measurement of one of the those angles in our pentagon.

The sum of our angles in our pentagon would then be A+A+A+A+A or 5A.

But we are also given that this equals 40x^2-65x+50.

So that means 5A=40x^2-65x+50.

If we divide both sides by 5 we can find what one of our angles is in terms of x.  So let's do that A=8x^2-13x+10.

So we want to know the sum of two our angles, we want to know what is A+A or 2A.  2A=2(8x^2-13x+10).  To obtain that I just multiplied both sides of A=8x^2-13x+10 by 2.
