multiply the polynomials
(x-6)(x2+2x-4)

Answer:

the answer is -2.1

Step-by-step explanation:

you get this by putting that -4 where the x is and solving so it would look something like this

1.7x+4.7    for x= -4

1.7(-4) + 4.7

-6.8 + 4.7

-2.1

Answer:

1/9

Step-by-step explanation:

This is basically 1/3*1/3. The way you do this is multiply the top numbers together and then the bottom numbers, so 1*1=1 and 3*3= 9 so your answer is 1/9. Hope this helps you!

Answer:

110

Step-by-step explanation:

Answer:

1, 4, 5

Step-by-step explanation:

a rational number is defined as a number that can be written as a fraction. so, 4 and 5 are automatically checked off. 1 also simplifies to plus or minus 11, which is a whole number, meaning it is automatically rational. 2 is not rational because there is no set pattern in the decimal, so it can not be written as a fraction. 3 is the same thing, so it is irrational.

Answer:

x = 7, -2

Step-by-step explanation:

==========================================

Work Shown:

x^2 - 5x = 14

x^2 - 5x - 14 = 0

(x-7)(x+2) = 0 .... this step is further explained below

x-7 = 0 or x+2 = 0

x = 7 or x = -2

The order of the solutions does not matter.

-------------------------

To factor x^2-5x-14, we need to find two numbers that multiply to -14 and add to -5. This is done through trial and error. I recommend making a table to help organize everything. See the diagram below.

After a bit of guess work, you should find that -7 and 2 are the two values we're after

-7 + 2 = -5

-7 * 2 = -14

This is why x^2-5x-14 = (x-7)(x+2)

Answer:

632.6

Step-by-step explanation:

Z = .3 right? It looks weird on my screen

Anyway, if z is .3 than this is how to solve

First you plug in 0.3 where the z would go, making the expression 622 + 2(0.3) + 10. Then you solve! (below)

622 + 2(0.3) + 10.

622 + 0.6 + 10.

622 + 10 + 0.6

632 + 0.6

632.6

I hope this helped! If you have any questions, feel free to message me :)

Let's find the value of x

x + 5 = 20

Subtract 5 from both sides

x = 15

x + 10 = 15 + 10 = 25

Number systems are systems in mathematics that are used to express numbers in various forms and are understood by computers. A number is a mathematical value used for counting and measuring objects, and for performing arithmetic calculations. Numbers have various categories like natural numbers, whole numbers, rational and irrational numbers, and so on. Similarly, there are various types of number systems that have different properties, like the binary number system, the octal number system, the decimal number system, and the hexadecimal number system.

A number system is a system representing numbers. It is also called the system of numeration and it defines a set of values to represent a quantity

Given:

height= 6 feet and 7 inches

Convert feet to meter

1 feet= 0.3048 meter

6 feet = 6* 0.3048

          =1.8288 meter

Now, convert inch to meter

1 inch= 0.0254 meter

7 inch = 0.0254 * 7

          =0.1778 meter

So,

6 feet and 7 inches= 1.8288 + 0.1778

                               = 2.0066 meter

Answer:

-3   2   6

Step-by-step explanation:

Consider this expression.

-3x2- 24x - 36

What expression is equivalent to the given expression?

-3 (x + 2)(x+6)

Drop down answer is in bold

The equivalent expression will be :  - 3 (x + 2) (x + 6)

We have the following expression -

[tex]-3x^{2}[/tex] - 24x - 36

We have to find out the equivalent expression of above expression.

Above expression can be expanded in the following way -

(x + 2)(x + 4) = x(x + 2) + 4(x + 4) = [tex]x^{2}[/tex] + 2x + 4x + 16 =   [tex]x^{2}[/tex] + 2x + 16

According to question -

 [tex]-3x^{2}[/tex] - 24x - 36

- 3 ([tex]x^{2}[/tex] + 8x + 12)

-3 ([tex]x^{2}[/tex] + 6x + 2x + 12)

-3 [x(x + 6) + 2(x + 6)]

-3(x + 2)(x + 6)

Hence, the equivalent expression will be :  -3(x + 2)(x + 6)
