The common difference in a geometric progression is the ratio between two successive terms.

Let's find the common difference in this sequence

[tex]r = \frac{-270}{-810} \\r = \frac{1}{3}[/tex]

The nth term of a geometric sequence is given as

[tex]T_n = ar^n^-^1\\[/tex]

The next two terms of this sequence will be 4th and 5th term.

The fourth term of this sequence is

[tex]T_4 = ar^4^-^1\\T_4 = -810 * (\frac{1}{3})^3\\ T_4 = -810 * \frac{1}{27}\\ T_4 = -30[/tex]

The fifth term of this sequence is

[tex]T_5 = ar^5^-^1\\T_5 = -810 * (\frac{1}{3})^4\\T_5 = -810 * \frac{1}{81} \\T_5 = -10[/tex]

The fourth and fifth term of this sequence is -30 and -10 respectively.

Answer:

x2+y2-x

Step-by-step explanation:

subtract like terms.

The required equivalent expression is [tex]x^2+y^2-x[/tex].

Important information:

The given expression can be written as:

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

Combining like terms, we get

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

On simplification, we get

[tex]x^2+y^2-x[/tex]

Therefore, the required equivalent expression is [tex]x^2+y^2-x[/tex].

Given:

Substitute the values into the expression to find the perimeter.

Answer: 28cm

Step-by-step explanation:

The perimeter formula for a rectangle = 2(l + w); where:

length = 9cm

width = 5cm

P = 2(l + w)

= 2(9 + 5)

= 18 + 10

= 28cm

Therefore, the perimeter of the cheese is 28cm

Anna  9 and Betty 15

Step-by-step explanation:

sum the parts of the ratio , 3 + 5 = 8 parts

divide number of sweets by 8 to find value of one part of the ratio

24 ÷ 8 = 3 ← value of 1 part of the ratio , then

3 parts = 3 × 3 = 9

5 parts = 5 × 3 = 15

Anna gets 9 sweets and Betty gets 15

Answer:

-10

Step-by-step explanation:

To find the answer to -2 - 8, we have to remember that when you subtract numbers, they go towards the negatives. So, since it is -2 - 8, you basically just add together the numbers but keep the negative sign, so the answer would be:

-2 - 8 = -10

Answer:

[tex]m = \frac{-1}{6}[/tex]

Step-by-step explanation:

You are solving for the slope (m). Use the following equation:

slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) =(-2 , 1)\\(x_2 , y_2) = (4 , 0)[/tex]

Plug in the corresponding numbers to the corresponding terms:

m = [tex]\frac{0 - 1}{4 - (-2)}[/tex]

[tex]m = \frac{-1}{4 + 2} \\m = \frac{-1}{6}[/tex]

[tex]m = \frac{-1}{6}[/tex] is your answer.

Check the picture below.

For the given similar polygons, the value of x equal to 30.

Two polygons are classified as similar when their angles are congruent and their sides are proportional.

If the polygons of this exercise are similar. You can write:

                                   [tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}[/tex]

Then,

                                    [tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}\\ \\ \frac{18}{12}=\frac{x}{20}=\frac{21}{14}[/tex]

It is possible to note that the scale factor is  [tex]\frac{3}{2}[/tex].  See it.

                                         [tex]\frac{18:6}{12:6}=\frac{3}{2} \\ \\ \frac{21:7}{14:7}=\frac{3}{2}[/tex]

Therefore, you can find x from:

                                      [tex]\frac{18}{12}=\frac{x}{20}\\ \\ 12x=18*20\\ \\ 12x=360\\ \\ x=\frac{360}{12} =30[/tex]
