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.
A will be 360/4
B will be pentagon
C will be 72
D will be hexagon
E will be 360/60
F will be 51.428571
Part A:Derrick is incorrect.
A yard is equivalent to 3 feet.
Thus, 20 yards will be equivalent to 60 feet.
The width is 20 yard and 2 feet. It's the same as 60 feet and 2 feet, or 62 feet. Thus, Derrick is incorrect.
Part B:Let's calculate the area of the parking lot.
We know the width is 62 feet from part A.
The length is 30 yards, or 90 feet.
Multiply the length and width to get the area in square feet.
The parking lot has an area of 5580 square foot.
It costs 2 dollars per square foot to repave the parking lot. Multiply the area by 2 dollars.
It will cost $11,160 to repave the whole parking lot.
Answer: =17x
Step-by-step explanation: hope this help, hope you understand it too.
Let's simplify step-by-step.
2x+5x+10x
Combine Like Terms:
=2x+5x+10x
=(2x+5x+10x)
=17x
13x + 13 + 2x = 2
15x + 13 = 2
15x = -11
