The most appropriate choice for percentage will be given by Percentage decrease in the investment is 22.22%
<h3>What Does Percent Mean?</h3>
Using a percentage of 100, we may express a ratio as a %.
Stock investments in this case decreased from $450 in 2013 to $350 in 2014.
Decrease in stock equals $100 ($450 - $355)
Decrease in percentage: 100/450 100 = 22.22%
<h3>What format does a percentage use?</h3>
The definition of percentage is "out of 100." In mathematics, percentages are used to represent parts of a whole, much as fractions and decimals. A total is considered to be made up of 100 equal parts when expressed as a percentage. The symbol % or, less commonly, the abbreviation 'pct' can be used to represent a percentage.

Answer:
3x (x-3)
Step-by-step explanation
3x^2 - 9x + 0
The equation.
3x^2 - 3^2 × x
What I did here is that I factored out 9x to 3^2 times x.
3x (3x^2 all over 3x - 3^2 × x/ all over 3x)
So that way I can divide the number in the parentheses by 3x to take 3x out of the parentheses to factor out.
3x (x^2-1 - (3^2-1) )
You simplify to get the final answer.
3x (x-3)
Final Answer.
I hope this helps!!!!
Answer:
See below.
Step-by-step explanation:
Let the side have a length x units .
The triangle formed by an altitude is a 30-69-90 triangle so the sides are in the ratio 2:1:√3 where √3 is the altitude. Therefore if the side of the triangle = x then altitude = √3 * x / 2 = √3x/2.
So we need to prove that 3x^2 = 4 (√3x/2)^2.
Simplifying:-
4 (√3x/2)^2 = 4 *( 3x^2/ 4) = 3x^2. This completes the proof,
