Fill in missing information to make the equality true: (... +2a)2 = … +12ab2+4a2.

Answer: Indeed, because the input value ranges from 0 to 12.

Step-by-step explanation:

To address this query, we first need to formulate a function that reflects the situation.

Every student engaging in community service earns the club $5

E(s) = 5 s

Where:

• E= total earnings
• n = number of students participating in community services (input value)

Indeed, since the input value n indicates how many students from the club engage in community service, and with the total number of students being 12, the input can indeed vary between 0 and 12.

Response: It will require him 1 hour and 35 minutes

For a quadrilateral to qualify as a parallelogram

i) both pairs of opposing sides must be equal

ii) Both pairs of opposing sides should be parallel

iii) Opposite angle pairs need to match

iv) Diagonals must bisect one another.

v) One pair of opposite sides should be both parallel and equal

In our case, it is given that AB || CD

Thus, we require either AD || BC

or we need that AB = CD

It has been specified that AB = CD as an option.

Therefore, the first option, A) stating AB ≅CD, is necessary to establish that ABCD is a parallelogram.
