Answer:

$x^3 + 4x^2 - 3x - 2$

Step-by-step explanation:

You need to multiply a binomial by a trinomial.

$(x-1)(x^2+5x+2) =$

Multiply each term of the binomial by each term of the trinomial.

$= x^3 + 5x^2 + 2x - x^2 - 5x - 2$

Now, combine like terms and write answer in descending order of exponent.

$= x^3 + 4x^2 - 3x - 2$

Answer:

x³ + 4x² - 3x - 2

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor

(x - 1)(x² + 5x + 2)

= x(x² + 5x + 2) - 1(x² + 5x + 2) ← distribute both parenthesis

= x³ + 5x² + 2x - x² - 5x - 2 ← collect like terms

= x³ + 4x² - 3x - 2

Slav-nsk [51]

Answer:

Convenience sampling.

Step-by-step explanation:

To gather information on customer satisfaction, a researcher goes into each store and interviews six randomly selected customers at each store. This sampling technique is called convenience sampling.

Convenience sampling can be defined as a sampling method which involves the researcher selecting or collecting data that is easily available or choosing the individuals who are easiest to reach in a population. It is a type of non-probability method of sampling where the first or easiest available data source is being used by the researcher without other requirements.

In this scenario, to gather information on customer satisfaction, the researcher went to the store most likely situated in a shopping mall to collect data from six (6) customers in each stores.

Some of the advantages of convenience sampling are low cost, data are collected quickly, lesser rules etc.

Steve paid 10% tax on a purchase of $40. Select the dollar amount of the tax and the total dollar amount Steve paid.

marta [7]

Amount of purchase that Steve made = $40
Percentage of tax that Steve needs to pay = 10%
Then
Amount of tax that Steve needs to pay for the purchase = (10/100) * 40
      = 1 * 4 dollars
      = 4 dollars
Then
The total amount including tax
that Steve needs to pay for the purchase = (40 + 4) dollars
   = 44 dollars
So the dollar amount of tax that Steve had to pay is $4 and the total amount that Steve had to pay was $44.

 5x = 300000

x = 300000/5

x= 60000

Leona = 60000*3 = 180000

Janet = 60000*2 = 120000
