Answer:

Option D. is correct.

Step-by-step explanation:

Let us assume that x = seven square root three plus two square root nine  

i.e. x = 7√3 + 2√9

⇒ x = 7√3 + 2 × 3 {Since 9 = 3²}

⇒ x = 7√3 + 6

Here, 7√3 is an irrational number and 6 is a rational number.

The answer is seven square root of three plus six is irrational because the sum of a rational number and an irrational number is an irrational number.

Therefore, option D. is correct.

Answer:

Option D

Step-by-step explanation:

Rational number is a number which can be expressed in the form \frac{p}{q} where, p and q are integers. A rational number in decimal form as a terminating or repeating decimal.

An irrational number is a number that can't be expressed in the form \frac{p}{q} and have a non-repeating, non-terminating decimal.

7\sqrt{3}+2\sqrt{9}= 7\sqrt{3}+2\times3=7\sqrt{3}+6

Square root of 9 is 3 as 3^{2}=3\times 3 =9

Here, 7\sqrt{3} is an irrational number as \sqrt{3} is an irrational number. The number 6 is a rational number.

So, the sum of a rational number and irrational number is always an irrational number.

Therefore, the correct option is option D

MrRa [10]
In the first survery \frac{336}{500} considered cola.
Assuming we can extrapolate this ratio, all we have to do is get the same ratio, but out of 2000 people.
\frac{336}{500} * \frac{4}{4}  \\  \frac{1344}{2000}
The answer is 1344 people.

What value for x will make the equation true?
Rama09 [41]

Answer:

C . 4

Step-by-step explanation:

step 1 : -3 multiply with inside of the ( 7x-5 )

= -21x + 15

step 2 : then it will be 21x + 15 = 87 + 3x

step 3 : switch between the odds into like this

21x - 3x = 87 - 15

step 4 : subtract it all

18x = 72

step 5 : bring 18 to the other side

x = 72/18

step 6 : to find the ans of x is just calculate them

x = 72 ÷ 18

= 4

Or you can do like these ⬇️

-3 ( 7x - 15 ) = 87 + 3x

21x + 15 = 87 + 3x

21x - 3x = 87 - 15

18x = 72

x = 72/18 or 72÷18

x = 4
