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

The polynomial product has the distributive property.

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

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

= 10x² - 2xy + 6x + 5xy - y² + 3y =

Step 2: Combine like terms.

= 10x² - y² + 3xy + 6x + 3y

Answer : 10x² - y² + 3xy + 6x + 3y

What is the volume of a rectangular Prism if it is scaled down by a factor of 1/10? Original volume is 135.

Snezhnost [94]

Answer:

$V=0.135\ units^3$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to teh scale factor elevated o the cube

Let

z ----> the scale factor

x ----> the volume of the dilated prism

y ----> the volume of the original prism

$z^3=\frac{x}{y}$

we have

$z=\frac{1}{10}$

$y=135\ units^3$

substitute

$(\frac{1}{10})^3=\frac{x}{135}$

solve for x

$(\frac{1}{1,000})=\frac{x}{135}$

$x=135/1,000=0.135\ units^3$

A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number greater than 2

Leona [35]

There is a 2/3 probability. Why? Well, the cube is numbered 1-6 so that is 6 numbers. Out of 6, there are 4 numbers greater than 2. Because of this, there is a 4/6 probability that a number greater than 2 will be rolled. 4/6 reduces to 2/3. As a percentage and decimal, the probability would be 66.66666666% or 0.66666666666 (repeating).

A leaf is falling from the top of a tree. The height of the leaf in feet, y, can be found using the function y = -3.5x + 28, whe

Bess [88]

Answer:

It took 8 seconds for the leaf to reach the ground.

Step-by-step explanation:

The height of the leaf in feet can be found using the function:

y = -3.5*x + 28

where x is the time in seconds the leaf has been in the air.

You want to know how long it took for the blade to reach the ground. That is, the time it took for the blade to reach a height of 0 feet. So, replacing this value in the expression:

0= -3.5*x + 28

and solving you get:

-28= -3.5*x

(-28)÷ (-3.5)=x

8=x

It took 8 seconds for the leaf to reach the ground.
