Answer: I think it’s E and D
Explanation:
Because they lie above the plane W not on the plane.
To solve this problem, you can split the shape into a triangle and a parallelogram.
You can do this by imagining/drawing a line from point A to point C>
Now you can work out the area of triangle ACB
1/2 x b x h
1/2 x 5 x 3
= 7.5
Now work out the area of the parallelogram ACDE
b x h
5 x 3 = 15
Add the areas together and then you have the answer
7.5 + 15 = 22.5
Line AE is NOT parallel to line BD. This is because the intercepts made by the lines and the transversals are not proportional
<h3>Parallel lines theorem</h3>
In the given diagram,
If
Then,
Line AE is parallel to line BD
From the given information,
|AB| = x = 9
|ED| = 5
|AC| = 9 + 11 = 20
|EC| =5 + 7 = 12
Thus,
20 × 5 = 9 × 12
100 ≠ 108
∴ The lines are not parallel
Hence, line AE is NOT parallel to line BD. This is because the intercepts made by the lines and the transversals are not proportional

Answer:
A=25
B=98
Step-by-step explanation:
You can see it as a 2-eq system.
Call A Joao's money and B Luiz's money. The sum is $123:
A + B = 123
As the half of Luiz's money + 1 is the double of Joao's money, we could represent this as:
(B/2) + 1 = 2A [this is what the last sentence says]
We can get the A value by dividing both sides by 2:
[(B/2) + 1]/2 = 2A / 2
B/4 + 1/2 = A
Then, replacing this A value on our first equation:
B/4 + 1/2 + B = 123
B/4 + 4B/4 = 123 - 1/2
(5/4)B = 122.5
Multiplying by (4/5) [or dividing by 5/4] to eliminate this 5/4:
(5/4) B * (4/5) = 122.5(4/5)
B = 98
Then we find A:
A = B/4 + 1/2 = 24.5 + 0.5 = 25
A=25
