Factor completely.<br><br> x^6 − 27

Katarina [22]

Answer:

$(x^{2}-3)(x^{4}+3x^{2}+9)$

Step-by-step explanation:

we know that

A difference of cubes can be factored like this

$a^{3}-b^{3}=(a-b)(a^{2}+ab+b^{2})$

In this problem we have

$x^{6}-27$

we know that

$x^{6}=(x^{2})^{3}$

and

$27=(3)^{3}$

Let

$a=x^{2}$

$b=3$

substitute

$(x^{2})^{3}-(3)^{3}=(x^{2}-3)(x^{4}+3x^{2}+9)$

An expression is shown below.

Natalka [10]

Answer:

see step-by-step

Step-by-step explanation:

It's not clear from your notation, so I will provide 2 answers.

3√(47x) = 24√(47)

3√(47)√x = 24√(47)

Divide both sides by √(47): 3√x = 24

Divide both sides by 3: √x = 8

Square both sides: x = 64

3√(47)x = 24√(47)

Divide both sides by √(47): 3x = 24

Divide both sides by 3: x = 8

The diameter of a circle X is 18 cm the diameter of circle Y is 31 cm which circle has the greater area and by how much you 3.14

Finger [1]

Area of a circle = (pi)(radius squared)
A of Circle X= (3.14)(18cm/2)squared

We need to divide the diameter in half to get the radius.
A of Circle X= (3.14)(9) squared
A of Circle X= (3.14)(81)
A if Circle X= 254.34 cm

A of Circle Y= (3.14)(31cm/2)squared

We need to divide the diameter in half to get the radius.
A of Circle Y= (3.14)(15.5) squared
A of Circle Y= (3.14)(240.25)
A if Circle Y= 754.39 cm

Find the difference in Area:
=Circle Y - Circle X
=754.39 - 254.34
=500.05 cm difference

Circle Y has the greater area of 754.39. It it greater than Circle X by 500.05 cm

First you bring the 9 over with the seven
$-2= \sqrt[3]{x+9}$
Now cube both sides
$-8=x+9$
Finally subtract 9 over and get
$x=-17$

Check
$7=9+ \sqrt[3]{-17+9}$
$7=9+ \sqrt[3]{-8}$
$7=9+(-2)$
7=7
