For each expression listed, is it a difference of squares? Explain yes or no and why or why not. Explain in enough detail so the
Harlamova29_29 [7]
<h2>Explanation:</h2><h2></h2>

If we can write a polynomial in the form a^2-b^2, then we can factor it as:

a^2-b^2=(a-b)(a+b)

In this problem, we have the following expressions:

1. \ y^5 - 25 \\ \\  2. \ 9m^2n^2-121  \\ \\ 3. p^{18} - q^{10} \\ \\ 4. 16r^2 - 27

  • For 1 and 4 we can't write this in the form a^2-b^2 so this is not a difference of squares.

  • For 2:

9m^2n^2-121 =3^2m^2n^2-11^2 \\ \\ =(3mn)^2-11^2 =(3mn-11)(3mn+11)

So we could write 2 as a difference of squares.

  • For 3:

p^{18} - q^{10}=(p^9)^2-(q^5)^2=(p^9-q^5)(p^9+q^5) \\ \\ \\ Remember: \ (a^m)^n=a^{mn}

So we could write 2 as a difference of squares.

Men and women aren’t equal evaluate this statement. Give some religous scriptures
svetlana [45]

Answer:

Indeed, men and women are not the same. They have structural differences in their genetic makeup that make them different and compatible with each other. In addition, they have differences in character, behavior, strength and even emotional sensitivity.

Even the scriptures themselves speak of differences between the two: according to the book of Genesis, the woman was created from the rib of Adam, the first man on earth. With this, the woman, theoretically, has one more rib than the man.
