We will verify each options
option-A:
![\sqrt{121}](https://tex.z-dn.net/?f=%5Csqrt%7B121%7D)
we can factor it
![\sqrt{121}=\sqrt{11*11}](https://tex.z-dn.net/?f=%5Csqrt%7B121%7D%3D%5Csqrt%7B11%2A11%7D)
![\sqrt{121}=\sqrt{11^2}](https://tex.z-dn.net/?f=%5Csqrt%7B121%7D%3D%5Csqrt%7B11%5E2%7D)
![\sqrt{121}=11](https://tex.z-dn.net/?f=%5Csqrt%7B121%7D%3D11)
so, this is not irrational.........Answer
option-B:
![\sqrt{65}](https://tex.z-dn.net/?f=%5Csqrt%7B65%7D)
Since, it can not be factored
so, this is irrational.........................Answer
option-C:
![\sqrt{36}](https://tex.z-dn.net/?f=%5Csqrt%7B36%7D)
we can factor it
![\sqrt{36}=\sqrt{6*6}](https://tex.z-dn.net/?f=%5Csqrt%7B36%7D%3D%5Csqrt%7B6%2A6%7D)
![\sqrt{36}=\sqrt{6^2}](https://tex.z-dn.net/?f=%5Csqrt%7B36%7D%3D%5Csqrt%7B6%5E2%7D)
![\sqrt{36}=6](https://tex.z-dn.net/?f=%5Csqrt%7B36%7D%3D6)
so, this is not irrational.........Answer
option-D:
![\sqrt{64}](https://tex.z-dn.net/?f=%5Csqrt%7B64%7D)
we can factor it
![\sqrt{64}=\sqrt{8*8}](https://tex.z-dn.net/?f=%5Csqrt%7B64%7D%3D%5Csqrt%7B8%2A8%7D)
![\sqrt{64}=\sqrt{8^2}](https://tex.z-dn.net/?f=%5Csqrt%7B64%7D%3D%5Csqrt%7B8%5E2%7D)
![\sqrt{64}=8](https://tex.z-dn.net/?f=%5Csqrt%7B64%7D%3D8)
so, this is not irrational.........Answer

<h3>How to plot the numbers on the number line?</h3>
The numbers are given as:
5.3, 5 1/5 and 5
We start by representing the numbers as decimals (i.e. real numbers).
So, we have:
5.3, 5.2 and 5
Reorder the numbers in ascending number (i.e. from least to greatest)
So, we have
5, 5.2 and 5.3
Next, we plot the numbers on a number line using a scale of 0.1
This can be visualized as
5 5.2 5.3
See attachment for the number line that compares the numbers 5.3, 5 1/5 and 5

- 10x - 5 + 5x
- 10x + 5x - 5
-5x-5
Answer:
7
Step-by-step explanation:
8 units separate -4 and 4
8 divided by 2 (which is the x of slope) is four
Four times 1 (which is y of slope) equals four
3+4 equals seven
(4,7)
Answer:
21
Step-by-step explanation:
If x was more than 1, then it would be impossible because fx would have to be even, but 4x+3 would be odd. Therefore, x must equal 1, and f must equal 7. This means that 3f=21
