Answer:

There is no solution

Step-by-step explanation:

Given the rational equation 2x^2 + 1/x-1 + x = 3 + 3/x -1

We are to find the value of x

Collect like terms

2x²+x-3 = 3/x-1 - 1/x-1

2x²+x-3 = 2/x-1

Cross multiply

(2x²+x-3) (x-1) = 2

2x³-2x²+x²-x-3x+3-2 = 0

2x³-x²-4x+1 = 0

Since we cannot factor the polynomial, hence there is no solution

Before answering the given question, you should know the difference between polygon and regular polygon. 

Polygon :- It is closed figure constitute of straight line having different measurements and also having varies angles.
Regular polygon :- It is also a closed figure constitute of straight lines which having equal measuresment and all the angles of the given polygon are equal .

There are different types of polygon based on the sides :-

A polygon having 3 sided called triangle ,having 4 sides called quadrilateral ,having 5 sides pentagon and so on.

<h3>Let's Begin :-</h3>

I have thought to make a 4 side polygon that is quadrilateral.

Steps of construction :-

Step - 1 :- Draw a 5 cm line AB horizontally
Step - 2 :- Then , From a point B, Draw a Vertical line of 5 cm and named it BC
Step - 3 :- Then, From a point C, Draw a horizontal line of 5 cm and named it CD
Step - 4 :- Now, join the line AD
Step - 5 :- Measure all the angles form by the 4 sides of the quadrilateral.

Result :-  All the angles are equal that is 90° each.

Conclusion :-  The above figure is square as it is having equal sides and angles.

<h3>Now, we have to find the sum of the angles of the polygon :-</h3>

Here, 

All angles are equal in measure 90°

Therefore, 

The sum of the angles of the given polygon

$\sf{ = 90{\degree} + 90{\degree} + 90{\degree} + 90{\degree} }$

$\sf{ = 180{\degree} + 90{\degree} + 90{\degree} }$

$\sf{ = 270{\degree} + 90{\degree} }$

$\sf{ = 360{\degree} }$

Hence, The sum of the angles of the above polygon is 360° .

Josh buys cucumbers that cost $0.62 per pound.He pays $2.79 for the cucumbers.

Sphinxa [80]

Please refer to the other post you saw.

Josh's estimate IS reasonable because when you have a number 5 or above after the decimal, you round up. Although it's reasonable to round up to 5 pounds, the actual amount is 4.5 pounds, or four and a half.

Does the following infinite series have a sum or not and does it converge or diverge?

iren [92.7K]

Answer:

Step-by-step explanation:

Please present these numbers as a list: 7, -21, 63, -189, ....

Otherwise it appears that you are adding them up, which is not the case.

We can tell that this is a geometric series because each new number is -3 times the previous number: -3(7) = -21, -3(-21) = 63, and so on. Let r = -3 and a = first number = 7.

The sum of an infinite geometric series exists if and only if |r} < 1. Here, |-3|, or 3, so in this case the sum of the series does not exist. That is, the series diverges.
