Find all values of the variable

The values of x for which the rational expression is undefined are -6 and -8.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a rational function:

\rm f(x) = \dfrac{3x+20}{x^2+14x+48}

As we know in the rational function denominator cannot be zero:

The values of x for which the rational expression is undefined.

x² + 14x + 48 = 0

\rm x_{1,\:2}=\dfrac{-14\pm \sqrt{14^2-4\cdot \:1\cdot \:48}}{2\cdot \:1}

\rm x_1=\dfrac{-14+2}{2\cdot \:1},\:x_2=\dfrac{-14-2}{2\cdot \:1}

x = -6, -8


Thus, the values of x for which the rational expression is undefined are -6 and -8.

What is 1 /7 as a decimal rounded to 3 decimal places?
Nostrana [21]

Answer:

0.143

Step-by-step explanation:

You need to convert 1/7 to have a denominator of either 100 or 10. We can do 100.

1/7 = ?/100

then you need to divide 100/7 to find the scale factor which in this case is 14.286

then you can insert it into the equation

1/7 = 1 * 14.286/100

you end up with

14.286/100

then you can dived the two

0.14286 is what you end up with

but since it says rounded to the 3rd decimal place you go to the 3rd which is 2.

To round it you look at the 4th number which is 8.

<em>5 and above give it a shove up</em>

So now its 0.143

Hope this helped :)

Help me with this?<br> ______________
Simora [160]

Answer:

Austin will have to buy 180 squares of carpeting.

Step-by-step explanation:

First find the dimension of the room. We do that by multiplying the width times the length and then subtracting the cut out region in the top right. And, in order to know how big that region we cut out is, we have to do a little subtraction.

We know the room is 18' long on the left side and 12' long on the right side. We subtract 12 from 18 to get 6, and we know that the cut out region is 6' long. We do the same thing with the width, 25' wide at the bottom minus 10' wide at the top and we see that the cut out is 15' wide.

18 x 25 = 450

6 x 15 = 90

450 - 90 = 360. The area of the room is 360 ft^{2}

Each piece of carpet is 2' by 1'. So for every 2' long, the piece of carpet is 1' wide. Each carpet piece will cover 2 ft^{2}. Divide 360 by 2 and you get 180.
