What is the product of 2x + y and 5x – y + 3?
andrew11 [14]
<h3>What is the product of 2x + y and 5x – y + 3?</h3>

<em>The polynomial product has the distributive property.</em>

<em>Step 1:</em><em> We have to distribute each term of the first polynomial to every term of the second polynomial.</em>

(2x + y) * (5x - y +3) = 2x(5x - y + 3) + y(5x - y + 3) =

= 10x² - 2<u>xy</u> + 6x + 5<u>xy</u> - y² + 3y =

<em>Step 2: </em><em>Combine like terms.</em>

= 10x² - y² + 3xy + 6x + 3y

Answer : 10x² - y² + 3xy + 6x + 3y

Michael’s haircut was 14.00 he gave a tip of 3.50 what percentage did Michael leave as a tip
Maurinko [17]

Answer:

D. 25%

Step-by-step explanation:

There are two ways that I do this. Both of them are probably not what your teacher tells you, but hey, I got the right answer.

The first method is to go through the answers and do 14 x .10, 14 x .20, and so on until you get 3.50.

The second method is to do 14/3.5, which equals 4. This means 14 can be broken up into 3.50 four times. So, 3.50 is 1/4 of 14. What is 1/4 of 100%? 25%.
