PLEASE ANSWER + BRAINLIEST!! Factor completely. 4k - 20k^9 = 3b^2 - 108 =

Neporo4naja [7]

$4k-20k^9=4k(1-5k^8)=4k\left[1^2-(k^4\sqrt5)^2\right]\\\\=4k(1-k^4\sqrt5)(1+k^4\sqrt5)=4k\left[1^2-(k^2\sqrt[4]5)^2\right](1+k^4\sqrt5)\\\\=4k(1-k^2\sqrt[4]5)(1+k^2\sqrt[4]5)(1+k^4\sqrt5)\\\\=4k\left[1^2-(k\sqrt[8]5)^2\right](1+k^2\sqrt[4]5)(1+k^4\sqrt5)\\\\=4k(1-k\sqrt[8]5)(1+k\sqrt[8]5)(1+k^2\sqrt[4]5)(1+k^4\sqrt5)$

$3b^2-108=3(b^2-36)=3(b^2-6^2)=3(b-6)(b+6)$

$Used:\ (a-b)(a+b)=a^2-b^2$

What fraction is represented by the portion of the figure that is NOT shaded? (2 out of 10 are shaded)

OverLord2011 [107]

Well let's see.

If the figure is split up into 10 pieces, then
each piece is 1/10 of the whole figure.

If 2 of the pieces are shaded, then
2/10 of the whole figure is shaded.

How many pieces are left ?

There were 10 pieces all together, and
2 of them are shaded. Hmmm. I think
there are probably (10 - 2) = 8 of them left
that are not shaded.

8 pieces makes 8/10 of the whole figure.

Licemer1 [7]

Answer:

Mildred is correct because she distributed 5 correctly

Step-by-step explanation:

We cannot tell exactly which solution goes with which student, but we believe you are saying ...

Mildred’s Solution:

5 (Negative 2 and one-fourth) = 5 (negative 2 minus one-fourth)

= negative 10 minus StartFraction 5 over 4 EndFraction

= negative 11 and one-fourth

This solution describes the correct distribution of 5. Whoever it belongs to gave the correct solution.
