Step-by-step explanation:

(2n³ - 3n⁴ + 7n) - (n³ - 8n⁴ - 7n) = 2n³ - 3n⁴ + 7n - n³ + 8n⁴ + 7n

  {Here -1 is distributed }

Each polygon is divided into a number of triangles. Find the number of triangles if the number of sides in a polygon is: (a) 6

Answers

Answer:

4 triangles

Step-by-step explanation:

the number of triangles in a polygon is (the number of sides in the polygon - 2)

The number of triangles inside a polygon with six sides are 4.

What is a polygon? What is a mathematical function, equation and expression?               polygon : A polygon can be defined as a flat or plane, two-dimensional closed shape bounded with straight sides.function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.

Given is that the number of sides in a polygon is 6.

If the polygon has {n} sides, then the number of triangle in a polygon is → (n – 2).For n = 6, the number of triangles would be - (6 - 2) = 4

Therefore, the number of triangles inside a polygon with six sides are 4.

Step-by-step explanation:

9/x + 2 = 20

Subtract 2 from each side

9/x + 2-2 = 20-2

9/x =18

Multiply each side by x

9/x *x = 18*x

9 = 18x

Divide each side by 18

What is the answer to 5(n-7)=2(n+14) work

Answers

Answer:

n = 21

Step-by-step explanation:

5(n-7)=2(n+14)

Distribute

5n -35 = 2n+28

Subtract 2n from each side

5n-2n -35 = 2n-2n +28

3n-35 =28

Add 35 to each side

3n-35+35 = 28+35

3n = 63

Divide by 3

3n/3 = 63/3

n =21

Answer:

The answer is n=21.

Step-by-step explanation:

To solve the equation for (n), start by using the distributive property on both sides of the equation. The distributive property is multiplying the sum of two or more addends by a number which will give the same result as multiplying each addend individually by the number and then adding the products together.

The equation will look like [tex]5n-35=2n+28[/tex] after using the distributive property. Next, add 35 to both sides of the equation, which will look like [tex]5n=2n+63[/tex], and then subtract (2n) from both sides of the equation, which will look like [tex]3n=63[/tex]. The next step is to simplify the equation, which will look like [tex]n=21[/tex], and the final answer to the equation will be [tex]n=21[/tex].

35 is 26% of what number?

Answers

Answer:

134.61 is the answer . hope This helps

Answer:

The answer is 134.61

Step-by-step explanation:

We have, 26% × x = 35

Or, 26/100 × x = 35

We have: x = 35 × 100/26

35×100 = 3,500

3,500 ÷ 26 = 134.61

x = 134.61

If you use a calculator, simply put 35×100÷26, which will give you the answer.

A farmer has 180 bushels of apples for sale at a​ farmer's market. He sells an average of 15 3/4 bushels each day. After 6 ​days, what is the change in the total number of bushels the farmer has for sale at the​ farmer's market?

Answers

If the farmer sells an average of 16 3/4 bushels each day, then after 6 days the farmer would have sold

16 3/4 * 6

We can rewrite the mixed number 16 3/4 as an improper fraction for easier multiplication

16 3/4 = 67/4, so

16 3/4 * 6 = 67/4 * 6

67/4 * 6 = 67/4 * 6/1 = 402/4 = 100 2/4 = 100 1/2 bushels sold after 6 days

If the farmer began with 180 bushels, then after 6 days the farmer has

180 - 100 1/2 = 79 1/2 bushels

8 feet long. The tables will be covered with paper tablecloths that extend
an extra 3 inches over each end (so they can be taped underneath). What
is the total length of paper needed to cover all the tables?

Answers

We have that the total length of paper needed to cover all the tables is

[tex]X=288.5ft[/tex]

From the question we are told that:

Number of tables [tex]n=36[/tex]

Length of table[tex]l=8[/tex]

Extension [tex]e=3 inch =>0.25feet[/tex]

Generally, the equation for the Total length  tables is mathematically given by

[tex]l_t=n*l\\\\l_t=36*8[/tex]

[tex]l_t=288ft[/tex]

Therefore with an extension of 0.25ft at both end we have the Total length of  tablecloths to be

[tex]X=l_t+2(e)\\\\X=288ft+2(0.25)[/tex]

[tex]X=288.5ft[/tex]

In conclusion

The total length of paper needed to cover all the tables is

A baker is building a rectangular solid box from cardboard to be able to safely deliver a birthday cake. The baker wants the volume of the delivery box to be 360 cubic inches. If the width of the delivery box is 3 inches longer than the length and the height is 4 inches longer than the length, what must the length of the delivery box be?
2 inches
5 inches
8 inches
9 inches

Answers

Answer:

5

Step-by-step explanation:

Solution is 8 in

Let´s call dimensions of the box

x  the length of the boxy the width  of the box    andh the height  of the box

According to the problem statement

y = x + 3     and    h = 4 in

The volume of the box is:

V = x×y×h       V = 360 in³

Then  V = x × ( x + 3 ) × 4     ( by substitution of y as a function of x )

360 = x × ( x + 3 ) × 4

Simplifying by 4

90 =  x × ( x + 3 )

90 = x² + 3x

We got a second degree equation, solving for x

x² + 3×x - 90 = 0

x₁,₂ = ( -3 ± √ (3)² + 4×90 )/2   ⇒   x₁,₂ = ( - 3 ± 19,21 )/2

x₁   ⇒  is a negative value    x = - 11,1  so we dismiss such solution

x₂  = 16.21/2

x₂  =  8.1 in

rounding to the nearest integer number we get the value for the length f the box

x₂ = 8 in        ⇒ x = 8 in

Answer:

Step-by-step explanation:

times mean multiplication and minus mean subtraction, I hope this helps.

An equation is formed of two equal expressions. An equation that fits Sarah's way of seeing the relationship is y = 3x - 2.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

As stated by Sarah that "the number of tiles in each figure was always 3 times the step number minus 2", this can be written in the form of an equation as shown below.

Number of tiles = [3 × (Number of steps)] - 2

Assume that the number of tiles is represented by y, while the number of steps can be written as x. Therefore, we can write the equation as,

y = 3x - 2

Now, let's check the equation,

When the number of steps is 3, the number of tiles is 7.

y = 3(3) - 2

y = 9 - 2

y = 7

Since the number of tiles is the same, therefore, the equation is correct.

Hence, an equation that fits Sarah's way of seeing the relationship is y = 3x - 2.
