Terms that have the same variables and the same exponents can be combined together.

5x - 12y + 8x + 2x^2 + 4x^2 =

= 5x + 8x - 12y + 2x^2 + 4x^2

= 13x - 12y + 6x^2

Answer: Second choice, 13x - 12y + 6x^2

5x - 12y + 8x + 2x² + 4x²

Combine like terms

You can keep the variables/exponents the same if you are adding or subtracting the same like terms (same variable to the same power)

5x - 12y + 8x + 2x² + 4x²

We can combine 5x + 8x and 2x² + 4x² because they are like terms; -12y will be left alone

13x - 12y + 6x² is your answer

How did you get -1? In the problem xm=x+z ,for x
lys-0071 [83]
Remember, we can do anything to an equation as long as you do it to both sides

and distributive proeprty, reversed
ab+ac=a(b+c)

xm=x+z
minus x from both sides
xm-x=z
xm-1x
undistribute x
x(m-1)=z
divide both sides by (m-1)
x=\frac{z}{m-1}

Which kind of decimals are irrational?
ella [17]

Answer:

D.) Those that never end and have no pattern

Definition:

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.

<em>Hope this helps : D</em>
