None of the options give the same fees for a session of x hours.
Given,
x + 20/2 = 3x
when two tutoring services with different rate plans charge the same fees for a session of x hours.
<h3>What is arithmetic?</h3>
In mathematics, it deals with numbers of operations according to the statements.
x + 20/2 = 3x
x + 10 = 3x
A) x= 10
10 + 10 = 3*10
20 ≠ 30
B) x=4
4 + 10 = 3 * 4
14 ≠ 12
C) x= -14
-14 + 10 = 3 * -14
-4 ≠ 42
D) x=-17
- 17 + 10 = 3 * - 17
-7 ≠ -51
Here, none of the options give the same fees for a session of x hours.
Thus, none of the options give the same fees for a session of x hours.

<h3>Answer:</h3>
4 m
<h3>Explanation:</h3>
If we let h represent the height of the sail, then its width is h/2. The area of the sail is given by ...
... A = (1/2)wh
Filling in the given information, we have
... 4 m² = (1/2)(h/2)h
... 16 m² = h² . . . . . . multiply by 4
... 4 m = h . . . . . . . . take the square root
Answer:
a) The coordinates of the missing vertex = (7, 8)
b) Area = 18 square units
Perimeter = 18 units
Step-by-step explanation:
a) We know three of the four vertices:
A: (4, 2) C ______ D(?)
B: (7, 2) | |
C: (4, 8) A |______| B
To find the coordinates of the missing vertex we need to calculate the distance in the x-direction from point A to point B:
Hence, the distance of point D from point C in the x-direction is:
Now, to find the coordinate in "y" we need to calculate the distance in the y-direction between point C and point A:
Then, the distance of point D from point B in the y-direction is:
Therefore, the coordinates of the missing vertex (point D) are:
b) The area of the rectangle is:
The perimeter is given by:
