If 4(x+2)-2(x-10)=0 , what is the value of x ?

The most commonly used explicit of an arithmetic sequence is given as,

an = a + (n - 1) d

Each term in the sequence can easily be solved/computed without knowing the other terms in the sequence. Now by using the given information, we can say that,

2nd row seat = 12+ 1x2

3rd row seat = 12 + 2 x2

nth seat = 12 + (n-1) x 2

16th row seat = 12 + (16–1) x2 = 42

Since the number of seats is increasing at a constant rate, we can calculate the average number of seats in each row by taking the average of the first and last rows,

Average number of seats per row = (12 +42)/2= 27.

So total seats = average per row x number of rows.

= 27 x 16 = 432.

The 2nd and 3rd term of an AP is found to be (a₂ = 95) and (a₃ = 110).

In Arithmetic Progression, the difference between the two numerical orders is a fixed number (AP). Arithmetic Sequence is another name for it.

We'd come across a few key concepts in AP that had been labeled as:

As shown below, the AP can also be referred to in terms of common differences.

Now, the given sequence is; 80, _, _, 125.

The series comprises of four given terms.

Let the first term be 'a₁' = 180.

The second term be 'a₂'.

The third term be 'a₃'.

And, the fourth term is 'a₄' = 125.

Use the nth term formula to find the common difference 'd'.

n-th term:  an = a + (n − 1) × d

a₄ = a + (n - 1)d

125 = 80 + (4 - 1)d

45 = 3d

d = 15

Thus, the common difference is 15.

The second term is calculated as;

a₂ = a₁ + d

a₂ = 80 + 15

a₂ = 95.

The third term is estimated as;

a₃ = a₂ + d

a₃ = 95 = 15

a₃ = 110

Therefore, the 2nd and third term of an AP is computed as 95 and 110.

The equation be I = √W/R  

Where I is the current.

W stands for electrical power.

R stands for resistance in ohms then the value of I = 1.414

A circuit's ability to transport electrical energy is referred to as its electric power. One joule per second, or one watt, is the SI unit of power. Similar to other SI units, watts have standard suffixes that refer to thousands, millions, and billions of watts as kilowatts, megawatts, and gigawatts, respectively.

Let the equation be I = √W/R

Where W and R are both within the square root symbol and 

I is the current.

W stands for electrical power.

R stands for resistance in ohms.

When W = 100, R = 25, to solve for the value of I for each set.

The probability for the arrow that land in the odd number is 1/2.

Probability:

Basically, the word probability define the possible way of occurring the event.

Given,

The spinner is divided into 8 equal sections.

Here we need to find if the arrow lands on a number, what is the probability that it will land on an odd number.

Let us consider that the spinner has 8 equal-sized sections numbered 1 to 8.

Since the sections have equal size, each section is equally probable.

The probability of falling on each section is therefore 1/8.

We know that, in the 8 sections,

There are four odd numbered sections.

Hence, probability is

=> 4/8

When we simplify it,

=> 1/2

Therefore, the probability for the arrow that land in the odd number is 1/2.

The simplification by combining like terms of 2(h + 2g) - (g - h) is 3(h + g).

According to the given question.

We have an expression 2(h + 2g) - (g - h).

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression

2(h + 2g) - (g - h).

Here 2h, and h and 2g and -g are the like terms.

So, we add and subtract coeffcients of h and g to simplify the given expression.

Therefore, the simplification of 2(h + 2g) - (g - h) is given by

= 2(h + 2g) - (g - h)

= 2h + 4g - g + h

= 3h + 3g

= 3(h + g)

Hence, the simplification by combining like terms of 2(h + 2g) - (g - h) is

3( h + g).

Answer:

x= 10 , DEG = 60 , GEF = 40

Step-by-step explanation:

Firstly the angle DEH is 90 degrees because of the red square indicating it.

That means the angle DEF is also 90 degrees.

To find the x you would do:

6x + 4x = 90

now add the 6x and 4x together:

10x = 90

now divide 10 from both sides to isolate the x:

x = 10

now you have your x which is 10.

For angle DEG you plug in the 10 for the x:

DEG = 6(10)

after that you multiply the 6 and 10:

DEG = 60

For angle GEF you plug in the 10 for the x:

GEF = 4(10)

after that you multiply 4 and 10:

GEF = 40

Using an arithmetic sequence, it is found that the perimeter when 106 triangles are put together is of 108 cm.

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

[tex]a_n = a_1 + (n - 1)d[/tex]

The perimeter of a figure is the sum of the outer sides of the figure. Hence, considering that all sides are 1 cm long, we have that:

Hence the first term and the common difference are given as follows:

[tex]a_1 = 3, d = 1[/tex]

Hence the 106th term of the sequence is:

[tex]a_{106} = 3 + 105 = 108[/tex]

The perimeter when 106 triangles are put together is of 108 cm.
