Need help thank you.

Answer:

x = 20

Step-by-step explanation:

The three angles make up a straight line.

A straight line has 180 degrees.

x + 3x + 100 = x80 Combine

4x + 100 = 180 Subtract 100 from both sides

4x = 180 - 100

4x = 80 Divide by 4

x = 80/4

x = 20

Expanding Logarithmic Expressions In Exercise, use the properties of logarithms to rewrite the expression as the sum, difference

kicyunya [14]

Answer:

$\\ ln(x^2) - ln(x^2 + 1)$ .

For values of x>0, it can be rewritten as $\\ 2ln(x) - ln(x^2 + 1).$

Step-by-step explanation:

For the expression:

$\\ ln(\frac{x^2}{x^2 + 1})$

We can apply this logarithmical property: $\\ ln(\frac{x}{y}) = ln(x) - ln(y).$

Then,

$\\ \frac{x^2}{x^2 + 1} = ln(x^2) - ln(x^2 + 1).$

If we assume values of x > 0 (non negative values for x), then the expression could be rewritten as follows:

$\\ \frac{x^2}{x^2 + 1} = ln(x^2) - ln(x^2 + 1) = 2 ln(x) - ln(x^2 + 1)$ , since $\\ ln(x^{n}) = n*ln(x).$

We have to remember that domain (all possible values x) for logarithmic function is for all x > 0, or mathematically expressed as:

Domain: $\\ {x | x \in R, x > 0}$

What is distributive property and one example of it?

mestny [16]

Example of distributive property: 4(2+3)
The first step is to multiply the 4 and the 2
It will now look like 8+4(3)
Now you must multiply the 4 and the 3
Then it will look like 8+12
In which 8+12=20
