Answer:

1. use the formula

(n-2)180

(20 - 2)180\\18 * 180 = 3240

2. use the formula

360/n\\360/12\\n = 30

3. There is only one at 360 degrees

4. there are 6 rotational symmetries and the number of reflectional symmetries would be 6 as you can see:

4. 7 + 14x<br> What does that mean
kotegsom [21]

7 + 14x means that a number x (x could be any real number) times 14 is added to 7.

So if x = 2:

7 + 14x = 7 + 14(2) = 28 + 7 = 35

Happy to help!

Andreas93 [3]

Doing factorization, we know that the factors of the given equation are ±√5 and ±10i.

<h3>What is Factorization?</h3>

In mathematics, factorization or factoring consists of writing a number or any mathematical item as a product of several factors, typically small or easier objects of the same.

For example, 3 × 5 is a factorization of an integer 15 and is a factorization of an equation x² – 4.

So, we have the equation:

x⁴ + 95x² – 500 = 0

Factorizing the above equation:

x⁴ + 100x² - 5x² - 500 = 0

x²(x² + 100) - 5(x² + 100) = 0

(x² - 5)(x² + 100) = 0

Solving further:

x² = 5

x² = -100

x = ±√5

x = √-100

Factors: ±√5 and ±10i

Therefore, doing factorization, we know that the factors of the given equation are ±√5 and ±10i.
