11) Which answer choice is equivalent to this
n +n +n + n
C) n.
A)
4+n
(B) An
D) n(n + 3)

Answers

Answer:

4n = B

Step-by-step explanation:

N + N + N + N

Pretend that n is equaled to 2

2 + 2 + 2 + 2 is also equaled to 4 * 2 because there are four 2s.

It is just the same as n + n + n + n = 4 * n

4 * n is also written as 4n which is B.

Lets also look at the other answers.

A does not make sense because 4 + 2 (the example) does not make sense.

C does not make sense because exponents deals with multiplying n and not adding it

D does not make sense because you can already tell using the Distributive property that it is wrong

The answer is b, I hope this helps!

Mai bikes 6 3/4 miles today, and Noah bikes 4 1/2
​

Answers

To find how many times the length of Noah's ride is compared to Mal's, you would divide the two mixed numbers:

6 3/4 divided by 4 1/2

Convert the mixed numbers to improper fractions:

27/4 divided by 9/2

To solve, multiply 27/4 by the reciprocal of 9/2:

27/4 * 2/9 = 3/2 or 1 and 1/2

So Mal's ride is 1.5 times longer than Noah's.

The height of the office building is 110.3 m

Let [tex]o[/tex] be height of office

[tex]h[/tex] be height of house

I believe it is very important for almost everyone, as it helps people feel relaxed and rejuvenate their spirits. It helps in experiencing a huge gradual range of emotions, such as despair, love, happiness, and even sadness. This specific type of music is important as it serves various purposes; it helps people in getting away from all the confusion in life and focus on lifes goals, such as a job opportunity, or just an accomplishment. This fascinating type of music makes me go into a zone, to just completely focus on whatever subject I need to. I believe Classical Music is something most people find beautiful, and I think others may not understand. My thoughts to do this speech immediately went to classical music and how I find it not just beautiful, but emotionally shatteringly, sometimes. Classical music, I believe, has the power of moving someone emotionally without speaking a word, it isn't just noises thrown together, it's something that a person has learned to create so carefully. Each note is put together to make the perfect piece. It can feature one instrument or multiple and can be replicated so that it's never lost.There is a world-renowned composer, I am sure all of you know, Ludwig van Beethoven, a German composer, and pianist, born December 1770, Bonn, Germany. Ludwig van Beethoven was a German composer and pianist. Beethoven remains one of the most admired composers in the history of Western classical music. His works span the transition from the classical period to the romantic era in classical music. They are famous for their great strength to empower you in his pieces of music. My most personal favorite is Beethoven Moonlight Sonata - Piano Sonata No. 14, this piece was designed to let you focus. Beethoven music you can listen to for hours, they are absolutely fascinating to hear and almost feel how wonderful it is. Thank you. 5. How might you be affected by the eloquence of a speech?
