Step-by-step explanation:
Answer:
2a^2 + 2a - 11
Step-by-step explanation:
(2a^2-5) +(-6+2a)
substitute
For this case we have the following polynomial:

To answer the question, what we must do is rewrite the polynomial in its standard form.
We have then that the polynomial will be given by:

Therefore, we have the ordered polynomial in descending form of exponents.
Therefore, the second term of the polynomial is:

Answer:
The second term of the polynomial is given by:

It would take 16 days
explanation
if it takes 15 for 4 people to work 8 hours to complete the task, it would be a total of 480 hours. I multiplied 15x4x8. i multiplied 5x6 to get 30. I have to find the third value so i divided 30 from 480 to get 16.
