<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

as Saturn revolves around the sun, it travels at a speed of approximately 6 miles per second. convert this speed to miles per mi
3241004551 [841]

Given:

Speed = 6 miles per second

If the Saturn revolves 6 miles in 1 second then the speed is:

\begin{gathered} In\text{ 1 second distance is 6 miles} \\ So\text{ in 60 second distance is =6}\times60\text{ miles} \\ =360 \end{gathered}

So speed in minutes is 360 miles per min.

In 3 minutes traveling distance is:

\begin{gathered} =360\times3 \\ =1080 \end{gathered}

Why must one leg of a triangle that the Pythagorean triple represents need an even-numbered length?
pashok25 [27]

Most of the square numbers are even.so if we need to find root over we need an even number to convert it to perfect square.

See the example below

  • P=3
  • B=4
  • H=5

\\ \ast\bull\rm\longmapsto H^2=P^2+B^2

\\ \ast\bull\rm\longmapsto H^2=3^2+4^2

\\ \ast\bull\rm\longmapsto H^2=9+16

\\ \ast\bull\rm\longmapsto H^2=25

\\ \ast\bull\rm\longmapsto H=\sqrt{25}

\\ \ast\bull\rm\longmapsto H=5

Some other triplets are

  • (6,8,10)
  • (5,12,13)
  • (8,15,17)
