Irrational number has unsolvable root overs.

Last two are now our options

$\\ \bull\tt\dashrightarrow \sqrt{25}=5$

Hence its not irrotational.

Hence

Option C is irrational.

Find the value of X

geniusboy [140]

Here, angle (3x-1) is supplementary with 5x, so their sum would be equal to 180

3x - 1 + 5x = 180
8x = 180 + 1
x = 181/8
x = 22.625

Hope this helps!

If f(x) = (x^1/2 - x)

Slav-nsk [51]

Well, you are subtracting g(x) from f(x) so:

√x-x-(2x^3-√x-x) which is:

√x-x-2x^3+√x+x (you have your signs wrong at the bottom of your post)

Now you would simply combine like terms (do your addition and subtraction of like terms)

-2x^3+2√x

So the answer is D.

Vamsi is X years old.his brother is 3 years elder to him. his uncle is 4 times his age and his aunt is 5 years younger than his

liberstina [14]

Step-by-step explanation:

<em>Vamsi is X years old</em>

Vamsi = X

<em>his brother is 3 years elder to him</em>

Brother = X + 3

<em>his uncle is 4 times his age</em>

Uncle = 4X

<em>his aunt is 5 years younger than his uncle</em>

Aunt = Uncle - 5

<em>what will be the age of his uncle 6 years from now</em>

= 4X + 6

<em>what are the ages of vamis brother, uncle and aunt?</em>

Assume Vamis = 15 years

Brother = X + 3 = 15 + 3 = 18

Uncle = 4X = 4 * 15 = 60

Aunt = Uncle - 5 = 60 - 5 = 55

<em>what will be the age of his uncle 6 years from now</em>

Uncle = 4X + 6 = 60 + 6 = 66

What equation results from completing the square and then factoring? x^2+22x=31 A.(x+22)^2=53 B.(x+22)^2=152 C.(x+11)^2=152 D.(x

Paladinen [302]

Answer:

$\boxed{\mathrm{Option \ C}}$

Step-by-step explanation:

=> $x^2+22x = 31$

=> $(x)^2+2(x)(11) = 31$

Since b = 11 , So $(11)^2$ needs to be added to both sides

Adding $(11)^2$ to both sides

=> $(x)^2+2(x)(11)+(11)^2 = 31+(11)^2$

Completing the square

=> $(x+11)^2 = 31+121$

=> $(x+11)^2 = 152$

john has us and foreign stamps in his album. the ratio of the numer of us stamps to foreign stamps is 5:2. after paul gives him

VLD [36.1K]

Answer:

The number of U.S stamp he has is <u>120</u>.

Step-by-step explanation:

John has us and foreign stamps in his album. the ratio of the number of U.S stamps to foreign stamps is 5:2.

After Paul gives him 12 foreign stamps the ratio becomes 2:1.

Now, to find the number of U.S stamps.

Let the U.S stamps be $x.$

And the foreign stamps be $y.$

Now, to solve by using cross multiplication method:

<em>So, the ratio is:</em>

$\frac{x}{y} =\frac{5}{2}$

By cross multiplying we get:

$2x=5y$

<em>Dividing both sides by 2 we get:</em>

$x=\frac{5y}{2}$ ......(1)

Now, after Paul gives him 12 foreign stamps the ratio becomes:

$\frac{x}{12+y} =\frac{2}{1}$

<em>By cross multiplying we get:</em>

$x=24+2y$

Putting the value of $x$ as we get in above equation (1):

$\frac{5y}{2} =24+2y$

<em>Multiplying both sides by 2 we get:</em>

$5y=48+4y$

<em>Subtracting both sides by 4y we get:</em>

$y=48.$

The number of foreign stamps = 48.

Now, to get the number of U.S stamps by putting the value of $y$ in equation (1):

$x=\frac{5\times 48}{2}$

$x=\frac{240}{2}$

$x=120.$

Therefore, the number of U.S stamp he has is 120.
