If we take both sides of the equation 
and <em>multiply either expression by 3</em>, the equality becomes
Multiplication of both sides of an equality by the same number keeps the equality true, and we call this property the multiplication property of equality.
You can compare fractions by using the benchmark fraction of 1/2. To use this in order to make comparisons, you will need to look carefully at what the numerator and The denominators are in a fraction. If the top number, the numerator is less than half of the denominator, then the fraction would be less then the benchmark 1/2. If the numerator is more than half of the denominator then the fraction would be more than the benchmark 1/2. For example, 3/4 is more than 1/2 because the numerator of three is more than half of the denominator 4.
The answer is:
x=-8
Because:
If you pick a number(-8) to fill in the equation written below
5x+20+5x=5x-20
After applying the -8 to x you get
-40+20-40=-40-20
When you simply the both sides you get
-60=-60
And that’s right -60 is equal to -60!
Answer:
3(x - a)(x - b)(x - c) when a + b + c = 3x .
Step-by-step explanation:
i don't know but this has to be right
Answer:
c
Step-by-step explanation:
Given that:
since cos (kπ) = 
Then, the series can be expressed as:
In the sum of an alternating series, the best bound on the remainder for the approximation is related to its 
term.
∴
