40% of 500 = 200
10% of 500 = 50 so just times it by 4
Answer:
x = 2i, x = -2i and x = 4 are the roots of given polynomial.
Step-by-step explanation:
We are given the following expression in the question:

One of the zeroes of the above polynomial is 2i, that is :

Thus, we can write

Now, we check if -2i is a root of the given polynomial:

Thus, we can write

Therefore,

Dividing the given polynomial:

Thus,

X = 4 is a root of the given polynomial.

Thus, 2i, -2i and 4 are the roots of given polynomial.
Answer:2.7=n
Step-by-step explanation:
n+27=11n
Move the variable to one side so subtract n
27=10n
Divide by 10
2.7=n
