The absolute value of 2 + 7<span> is 5.</span>
The factor of f(x) is (x-(4-13i))
If a polynomial function f(x) has roots 4 – 13i and 5
One of the complex roots is 4-13i
If we have one complex root then there should be one more complex root.
<h3>What is the complex root?</h3>
complex roots come in pairs like (a+ib) and (a-ib)
so another complex root for 4-13i is 4+13i
If 'a' is a root then the factor is (x-a)
4+13i is a root
So the factor is (x-(4-13i))

Answer:
20 people
Step-by-step explanation:
Let n represent the number of people served. If each ate 1/5 of a pizza and there are 4 pizzas, we have ...
(1/5)·n = 4
The solution can be found by multiplying both sides of the equation by 5.
5(1/5)n = 5(4)
n = 20
20 people could be served.
