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.
Y/5.....the quotient of y and 5
14.1 - w....the difference of 14.1 and w
9n + 1....the product of 9 and a number (n), increased by 1
(z/8) - 9.....9 less then the quotient of z and 8
15 - (1.5/d) ....15 decreased by the quotient of 1.5 and a number (d)
Answer i've done the math multiple times and everytime i get the answer 21,950. i don't think i'm doing the math wrong, maybe try asking the teacher or whoever is the one grading it cause it could be a typo or something like that.

Answer:
448 kilometers
Step-by-step explanation:
So, since the car goes 112 kilometers in one hour, you need to multiply 112 by 4.
112*4=448
The police car drives 448 miles in 4 hours.
