Answer:
x=72
Step-by-step explanation:
x-20=52
x=72
This means Square root (^1/2). this is kind of hard to read. anyways. 32^(1/2) separates into 4^(1/2) and 8^(1/2), which further separates into 4^(1/2) and 2^(1/2), root 4 becomes 2, their are two root 4's, so you get 2 x 2, and you are left with 2^(1/2) now why go to all this trouble. because now you can multiply the 4 you created (2x2) times, the 7... giving you 28*2^(1/2) now subtract it from the the other one with root 2. -5*2^(1/2), giving you 23*2^(1/2)-...idk what that last bit is. if its a odd number then this is the end of the problem, if you can get it to root 2. then do that and simplify.
So what we are going to do is subtract 350 minus 36percent. That is 224. So there are 224 students in this year's 6th grade class!
Hope this helps!

Answer:
Option (1) will be the answer.
Step-by-step explanation:
Coordinates of the points A and B lying on the line f are (0, 2) and (2, 0) respectively.
Slope of the line f,
![m_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=m_%7B1%7D%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
![m_{1}=\frac{2-0}{0-2}](https://tex.z-dn.net/?f=m_%7B1%7D%3D%5Cfrac%7B2-0%7D%7B0-2%7D)
After dilation of line f by a scale factor of 2, coordinates of A' and B' will be,
Rule for dilation,
(x, y) → (kx, ky)
Where k = scale factor
A(0, 2) → A'(0, 4)
B(2, 0) → B'(4, 0)
Slope of line f',
![m_{2}=\frac{0-4}{4-0}](https://tex.z-dn.net/?f=m_%7B2%7D%3D%5Cfrac%7B0-4%7D%7B4-0%7D)
![m_{2}=-1](https://tex.z-dn.net/?f=m_%7B2%7D%3D-1)
Since, ![m_{1}=m_{2}=-1](https://tex.z-dn.net/?f=m_%7B1%7D%3Dm_%7B2%7D%3D-1)
Therefore, both the lines f and f' will be parallel.
Option (1) will be the answer.
