What is the quotient 6x3+2x2−xx

DiKsa [7]

The quotient of 6x^3+2x^2−x and x is 6x^3+2x^2−x divided by x

The value of the quotient 6x^3+2x^2−x by x is 6x^2 + 2x - 1

<h3>How to determine the quotient</h3>

The quotient expression is given as:

6x^3+2x^2−x divide by x

The above means that,

We divide 6x^2 by x, we divide 2x^2 by x and we divide -x by x.

So, we have:

6x^3+2x^2−x divide by x = 6x^2 + 2x - 1

Hence, the value of the quotient 6x^3+2x^2−x is 6x^2 + 2x - 1

of 320 consumers polled, some purchase blu-ray movies, some only purchase movies on dvd, and some do both. if 300 people polled

Helga [31]

Answer:

20 people only buy dvds.

Step-by-step explanation:

There are two groups in this problem. One group of people that buys dvds and one that buys blu rays. The total amount of people who buy blu rays is 300, but there's an intersection between the groups and the size of this is 280 people who actually buy both. In order to find out how many people only buy DVDs we first need to figure out how many only buy blu-rays. That is:

people who only buy blu rays = people who buy blu rays - people who buys blu rays and dvds

people who only buy blu rays = 300 - 280 = 20

We can now calculate the amount of people who only buy dvds and that is:

people who only buy dvds =total amount of people - ( people who only buy blu rays + people who buy both)

people who only buy dvds = 320 - (20 + 280) = 320 - 300 = 20 people
