Answer:
x = 2 assuming uppercase is variable and lower case is multiplication symbol
Step-by-step explanation:
The length of side EF is the average of the lengths of the bases AB and CD of trapezoid ABCD.
EF = (8 + 20)/2 = 14
Trapezoid EF has bases 14 and 20.
The height of trapezoid EFCD is half the height of trapezoid ABCD, or 6.
A = (B + b)h/2 = (20 + 14) * 6 / 2 = 102
Answer: The area of trapezoid EFCD is 102 square units
Answer: A. $1.42
Explanation:
-Postcards = P
-large envelope = E
14p + 5e = 12 or 5e = 12 -14 p
10p + 15e = 24.8
5e = 12 - 14 p multiply by 3
15e = 36- 42 p
Combine 10p + 15e = 24.8 and 15e = 36- 42 p
That equals 10p + 36 - 42p = 24.8
10p + 36 - 42p = 24.8
11.2 = 32 p
P = 0.35
Bring down the equation 5e = 12 - 14p and substitute
5e = 12 - 14p
5e = 12 - (14 x 0.35)
5e = 12 - 4.90
5e = 7.10
e = 1.42

Formula for Circle if you know the Diameter - (π/4) × D2 = 201.06
Step-by-step explanation:
D = Diameter
π = Pi or 3.14...
You would usually round the answer to the nearest hundredth, so if you are looking for the answer, the answer would be 201.06
Answer:
The answer to your question is 8649 persons
Step-by-step explanation:
Data
Equation y = 11.89x - 15345.2
Year = x = 2018
Process
1.- Just substitute x in the equation
y = 11.89 (2018) - 15345.2
2.- Multiply 11.89 by 2018
y = 23994.02 - 15345.2
3.- Subtract to find x
y = 8648.82
4.- Conclusion
There was 8649 persons in 2018.
