Answer:

Step-by-step explanation:
2a is a common factor of the two terms:

Huh english is this spanish !
Since AB = CD the trapezoid is isosceles, which means that ∡A = ∡D
Therefore also ∡2 = ∡3 (they are half of the congruent angles)
For the properties of parallel lines (BD and AD) crossed by a transversal (BD) we have ∡3 = ∡CBD.
Now consider triangles AOD and BCD:
∡OAD (2) = ∡ADO (3) = ∡CBD (3) = ∡CDB (4)
T<span>he sum of the angles of a triangle must be 180°, t</span>herefore:
∡AOD = 180 - ∡2 - ∡3
∡BCD = 180 - ∡3 - ∡4
∡AOD = ∡BCD because their measure is the difference of congruent angles.
VARIABLES:
[x] Yearbook Club (expression: x)
[y] Drama Club (expression: x + 12)
EQUATIONS:
#1 x + y = 72
#2 y = x + 12
Now we shall use the method of substitution to solve.
FINDING X:
#1 x + (x + 12) = 72
#2 2x + 12 = 72
#3 2x = 60
#4 x = 30
The amount of students in the yearbook club: 30
The amount of students in the drama club: 72 - 30 = 42
If you can, please give me brainliest. Thank you!
Since their is no poem, I'm just guessing your answer is They never forgot.
