The answer is (C) 2x+1/ 2x+5.

This is just finding like terms.

Like terms are terms that are the same, like 2x and 3x for example, would be like terms. (This is not in the problem by the way.) Just divide the like terms, and that's your answer.

I tried to give a good explanation but I'm super tired. Just trying to help.

The sum of 9 and a number is twice a number plus 14. Write an equation.

Olin [163]

Answer:

9+x = 2y+14

Step-by-step explanation:

It says 9 plus a number, so plug in x for 'a number', and it says 'is twice a number plus 14'. Plug in '=' for is another variable for 'a number', and last but not least, just put +14 for plus 14

Find irrational number between 5, 25 and 5, 26

iragen [17]

Answer:

The answer is 2.5135145

Step-by-step explanation:

The irrational number between 5,25 and 5,26
2.5135145...
The number is non-terminating and non-recurring. Hence, it is an irrational number.
A real number that cannot be expressed as a simple fraction is called an irrational number.
It is impossible to express in terms of a ratio.
If N is irrational, it is not equal to p/q, where p and q are integers and q is not equal to 0.
Example: √2, √3, √5, √11, √21, π(Pi) are all irrational.

A square carpet of side length 9 feet is designed with one large shaded square and eight smaller, congruent shaded squares, as s

Pepsi [2]

Answer:

$3\sqrt{3} + 72$

Step-by-step explanation:

I attached an image to aid the understanding of the question.

Looking at the image, we see that the 8 shaded parts are congruent, as affirmed in the question as well. And we are told that T = 3, this implies that the area of the square with T as it's side is 9ft². Since all the 8 squares are congruenrt, it means each square has its area to be 9. Therefore, the total area of the 8 shaded squares will be:

$9 \times 8 = 72ft^{2}$

It remains the area of the shaded square with side S.

From the question, we have the following ratio:

$\frac{9}{S} = \frac{S}{T}[\tex]But[tex]\frac{9}{S} = \frac{S}{3}[\tex]Multiplying through by 3S we have27 = S² and this gives:[tex]S = \sqrt{27} = 3\sqrt{3}$

I did not add ± because length is always positive, so the case of negative is eliminated.

Now the areas of S is $3\sqrt{3}$

Therefore, the total area of the shaded squares is

$3\sqrt{3} + 72$
