Answer:

  -a^2 - a + 12

Step-by-step explanation:

You only need to find the products of the first and last terms to determine the correct answer:

  (-a)(a) = -a^2

  (3)(4) = 12

You're looking for an expression with -1 as the leading coefficient and +12 as the constant. There is only one choice like that:

  -a^2 - a + 12

Answer:

Subject B.

Step-by-step explanation:

It is given that,

There are total four subjects, namely A, B, C and D.

Out of these four subjects, we have, Subject B wants to impress the researcher above everyone while the other subjects do not care.

Since, Subject B wants to impress the researcher, they would want to use any means as possible so that the researcher gets amazed by them.

For this, it is highly possible that they will start answering questions in a way that makes them impressive, which would lead them to not answer questions honestly.

While the other subjects do not care whether the researcher is impressed, this will make them give the answer honestly.

Hence, Subject B is least likely to answer the questions honestly.

Vikki [24]
Number of apples purchased = A
Cost of each apple = 15 cents
Then
The total cost of 15 apples = 15A
Number of bananas purchased = B
Cost of each banana = 10 cents
Then
Cost of 10 bananas = 10B
So
The total value of purchase = 15A + 10B
So the correct option among all the options given in the question is option "D",. I hope the procedure is clear enough for you to understand. Using this procedure it will be possible for you to answer similar questions with ease and without requiring any help from outside.
