Answer: 8x^2 -4x -7

Step-by-step explanation: the x^2 term comes first, followed by the x, then the constant which in this case is -7

so it would be 8x^2 -4x -7

The polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.

To write the polynomial -7 + 8x² - 4x in descending order, we arrange the terms from highest degree to lowest degree.

Here's how to do it step by step:

Step 1: Identify the degree of each term:

The term -7 has a degree of 0 (since it is a constant).

The term 8x² has a degree of 2 (since it has a variable raised to the power of 2).

The term -4x has a degree of 1 (since it has a variable raised to the power of 1).

Step 2: Arrange the terms in descending order based on their degrees:

Start with the term with the highest degree and proceed in decreasing order. In this case, we have only three terms, so we start with the highest degree term:

8x² (degree 2)

Next, we consider the next highest degree term:

-4x (degree 1)

Finally, we have the constant term:

-7 (degree 0)

Step 3: Write the polynomial in descending order:

Putting the terms together in descending order, we have:

8x² - 4x - 7

So, the polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.

Answer:

-30 - 15e

Step-by-step explanation:

given -7(3e + 4) + 6e - 2, we can distribute -7 to parenthesis

-21e - 28 + 6e - 2, then we add like numbers

-15e - 30

Answer:

-15e - 30

Step-by-step explanation:

-7(3e + 4) + 6e - 2

Simplify:

-21e + (-28) + 6e - 2       (distribute -7 to 3e + 4)

-21e + 6e - 28 - 2          (combine like terms)

-15e - 30                        (combine like terms)

The estimates of the square roots and cube roots using the attached process are;

1) √15 = 3.81

2) √44 = 6.6.

3) √81 = 9

4) ∛12 = 2.88.

5) ∛125 = 5

6) ∛320 = 6..8

Perfect squares from 1 to 100; 4, 9, 16, 25, 36, 49, 64, 81, 100

Perfect cubes from 1 to 1000; 1, 8, 27, 64, 125, 216, 343, 512, 729 and 1000.

1) √15;

The nearest perfect squares to it are; 9 and 16

Thus; √9 < √15 < √16

⇒ 3 < √15 < 4

This means that √15 is between 3 and 4.

Since 15 is closer to 16 than 9, it means √15 is closer to 4 and thus, we can estimate √15 as 3.81.

2) √44;

The nearest perfect squares to it are; 36 and 49

Thus; √36 < √44 < √49

⇒ 6 < √44 < 7

This means that √44 is between 6 and 7.

Since 44 is closer to 16 than 9, it means √44 is closer to 6 and thus, we can estimate √44 as 6.6.

3) √81

This is a perfect square and the method used to estimate other non-perfect square doesn't apply here. Thus; √81 = 9

4) ∛12

The nearest perfect cubes to it are; 8 and 27

Thus; ∛8 < ∛12 < ∛27

⇒ 2 < ∛12 < 3

This means that √12 is between 2 and 3.

Since 12 is closer to 8 than 27, it means ∛12 is closer to 2 than 3 and thus, we can estimate ∛12 as 2.88.

5) ∛125

This is a perfect cube and the method used to estimate other non-perfect cubes doesn't apply here. Thus; ∛125 = 5

6) ∛320

The nearest perfect cubes to it are; 216 and 343

Thus; ∛216 < ∛320 < ∛343

⇒ 6 < ∛320 < 7

This means that ∛320 is between 6 and 7.

Since 320 is closer to 343 than 216, it means ∛320 is closer to 7 than 6 and thus, we can estimate ∛320 as 6..8

Answer:

20%

Step-by-step explanation:

First you must find the difference between the original price ($26.95) and the discounted price ($21.56)

26.95-21.56=5.39

Second find x

% of = #*x

Meaning

5.39=26.95*x

Divide 5.39 by 26.95

0.2=x which equals 20%
