It would be an A if i'm correct.
Answer:
The answer is 36
Step-by-step explanation:
If you do 27÷3 you get 9. So if it's 4 weeks you just add 9 which is 36
If complex coefficients are allowed, the answer is 3.
If the polynomial must have real coefficients, then each complex root comes as a pair of complex conjugate roots.
Root -5 is real, so that is 1 root, and degree 1.
Root 1 + 4i is complex, so it must come with its complex conjugate, 1 - 4i. This adds 2 roots to the polynomial, and now we're up to degree 3.
Root -4i is also complex. It also must come with its complex conjugate, 4i. That adds two more roots, and the degree is 5.
Answer: The least possible degree is 5 with real coefficients.
Answer:
The answer is A I believe
Step-by-step explanation:
<span>Seven times a number minus the number is -48.
7x - x = -48
6x = -48
x = -48/6
x = -8
Answer is </span>a. the number is -8
