Answer:

x=5

Step-by-step explanation:

CE = EB since E is the midpoint of CB (proven by AD intersecting it).

If CE=EB, then:

2x=15-x\\

<em>Add </em>x<em> to both sides</em>

3x=15\\

<em>Divide both sides by 3</em>

x=5

Step-by-step explanation:

What is the cube root of 27what is the factorization of 216x^12 - 64
elena-14-01-66 [18.8K]

Answers:

1) 27 is the same as multiplying three times three times three:

(3)(3)(3)={3}^{3}=27    (1)

Now, the cube root of 27 can be written as:

\sqrt[3]{27}={(27)}^{\frac{1}{3}}    (2)

Knowing the information given by (1) we can rewrite (2) as:

{({3}^{3})}^{\frac{1}{3}}

Applying the rule of exponents with the same base, which in this case is 3:

{(3)}^{3(\frac{1}{3})}=3

Finally:

\sqrt[3]{27}=3

2) We have the following expression:

216{x}^{12}-64

That can be factored by taking the common factor, which in this case is 8:

8(27{x}^{12}-8)

Then:

216{x}^{12}-64=8(27{x}^{12}-8)
