Answer:

[tex](3x-y)(x+y)^2[/tex]

Step-by-step explanation:

[tex]3x^3-x^2y+6x^2y-2xy^2+3xy^2-y^3[/tex]

Multiply and combine like terms.

[tex]3x^3+xy^2-y^3+5xy^3[/tex]

Consider [tex]3x^3+xy^2-y^3+5xy^3[/tex] as a polynomial over variable x.

[tex]3x^3+5xy^2+y^2x-y^3[/tex]

Find one factor of the form kx^m +n, where kx^m  divides the monomial with the highest power 3x^3  and n divides the constant factor −y^3 . One such factor is 3x−y. Factor the polynomial by dividing it by this factor.

[tex](3x-y)(x^2+2xy+y^2)[/tex]

Consider [tex]x^2+2xy+y^2[/tex]. Use the perfect square formula, [tex]a^2+2ab+b^2[/tex] = [tex](a+b)^2[/tex], where a=x and b=y.

[tex](x+y)^2[/tex]

Rewrite the complete factored expression.

[tex](3x-y)(x+y)^2[/tex]

Answer:

  1. adjacent: ACB, BCD and BCD, DCE. vertical: ACB, DCE and BCD, ECA

  2. adjacent: KGJ, JGI and HGM, MGK. vertical: JGI, MGL and HGM, KGJ

  3. adjacent. x = 49°

  4. adjacent. x = 71°

Step-by-step explanation:

As I noted in the attachment, vertical angles are formed from opposite rays (lines that cross). They share only a vertex. Each of the crossing lines makes up one side of each of the vertical angles. (You can think of each line as being made of opposite rays from the vertex of the angle.)

Adjacent angles share both a vertex and one side. (They do not overlap.) For example, in Figure 2, angles KGM and LGM are not adjacent, even though they share verex G and side GM. This is because they overlap. In that figure, angles KGL and LGM are adjacent angles.

__

1. To identify adjacent angles, choose a ray and make note of the angles on either side of it.

  adjacent: {ACE, ACB}, or {BCA, BCD}, or {DCB, DCE}, or {ECD, ECA}

To identify vertical angles, choose two crossing lines and one of the 4 spaces between them. The other vertical angle will be non-adjacent, in the opposite space of the same size.

  vertical: {ACB, ECD}, or {ACE, BCD}

__

2. adjacent: any of the pairs {KGJ, JGI}, {JGI, IGH}, {IGH, HGM}, {HGM, MGL}, {MGL, LGK}, {LGK, KGJ}.

Note that these are the nearest, smallest pairs of adjacent angles. This is usually what we are talking about when we refer to adjacent angles. We could add to the list pairs like {IGH, IGK}, {IGM, IGL}.

 vertical: (lines IL, HK) {IGH, LGK} or {IGK, LGH}; (lines IL, MJ) {IGM, LGJ} or {IGJ, MGL}; (lines HK, MJ) {HGM, KGJ} or {HGJ, KGM}

__

3. The angles share a ray, so are adjacent. Together, they make up a right angle, so they are complementary.

  x = 90° -41°

  x = 49°

__

4. The angle share a ray, so are adjacent. Together, they make up a linear angle, so are supplementary.

  x = 180° -109°

  x = 71°

Step-by-step explanation:

Answer:

No. of drinks sell by them in an hour=26/2=13

So,No. of drinks sell by them in 12 hours=

[tex]12 \times 13 = 156[/tex]

Hence, They sell 156 drinks in 12 Hours and 312 drinks in a day.

Answer:

L = 36

Step-by-step explanation:

"A triangle with a height of 3 cm and a base  of x cm is the result of reducing each  dimension by a scale factor of one-third"

We are looking for the original. This triangle was reduced by 1/3, so we would have to mulitply by 3 to get the original triangle measurements.

height = 3 x 3 = 9

length = x * 3

"The area of the original triangle is  162 cm²."

Area = Base x Height/2

162 = (x*3) * 9/2

324 = (x*3)*9

36 = x*3

x = 12

What was the original length of  the base?"

Length = x * 3

            = 12 * 3

Length = 36

Answer:

X = 35

Step-by-step explanation:

Since the line is crossing two parallel lines the measurements are equal then you solve for X.

2X + 20 = 3X - 15

-2X           -2X

20 = X - 15

+15      +15

35 = X

Answer:

x=35

Step-by-step explanation:

The expressions are corresponding angles which are congruent.

Set the two equations equal to each other.

2x+20=3x-15

Add and subtract like terms

35=1x

Divide:

35/1=35

X=35

Hope this helps! :)

Correct me if I'm wrong!

Answer:

x=11

Step-by-step explanation:

4x + 3 = x+ 2x + 14

4x + 3 = 3 x + 14

4x - 3x = 14 -3

x= 14 - 3

x= 11

Answer:

x=11

Step-by-step explanation:

Distribute :

4x + 3 = x + 2( x+ 7)

4x + 3 = x + 2x + 14

Combine like terms :

4x + 3 = x + 2x + 14

4x + 3 = 3 x+ 14

Subtract 3 from both sides of the equation :

4x + 3 = 3x + 14

4x + 3-3 = 3x + 14 -3

Simplify :

what ever way you know how to subtract the numbers you should get this answer :

4x = 3x + 11

Subtract 3 from both sides of the equation :

4x = 3x + 11

4x - 3x = 3x + 11 - 3x

Simplify :

combine like terms

multiply by 1

combine like terms

x= 11

Answer: exponent

Step-by-step explanation:

because 5 is bigger and bolder

Given:

The set of integers in the options.

-13 , 4, 0, -8

-5 , -2, 3, 1

-12 -18 , -4 , 7

-15, 6 , -9 , -21

To find:

The set of integers that is ordered from least to greatest.

Solution:

We know that the larger negative value is the smaller value and the larger positive value is the greater value.

Ordered from least to greatest means first we need to write the smallest value, write the value larger than and the greatest value occurs at the end.

In option A, we have -13 , 4, 0, -8. Here, 4>0. So, the option A is incorrect.

In option B, we have -5 , -2, 3, 1. Here, 3>1. So, the option B is incorrect.

In option C, we have -12 -18 , -4 , 7 Here, -12>-18. So, the option C is incorrect.

In option D, we have -15, 6 , -9 , -21. Here, 6>-9. So, the option D is incorrect.

Therefore, all the options are incorrect.

Option B is correct. I did the test and it shows 100% I hope it helped!

Answer:

can you put it for clear in a sentice

Step-by-step explanation:

Answer:

Since An/An-1 = r

(1/An)/(1/An-1) = An-1/An = 1/r

so, the ratio between terms is still constant.

Step-by-step explanation:

If an is defined as a geometric sequence, is the sequence 1/an also a

geometric sequence because the ratio between terms remain constant.

Suppose the initial term of a geometric sequence is a and the term by which we multiply the previous term to get the next term is r

Then the sequence would look like

[tex]a, ar, ar^2, ar^3, \cdots[/tex]

 (till the terms to which it is defined)

Thus, the nth term of such sequence would be[tex]T_n = ar^{n-1}[/tex]

Since An/An-1 = r

(1/An)/(1/An-1) = An-1/An = 1/r

Therefore, the ratio between terms is still constant.
