Answer:

Step-by-step explanation:
Here we are given that a polynomial has zeros as 2 , i and -i . We need to find out the cubic polynomial . In general we know that if
are the zeros of the cubic polynomial , then ,
Here in place of the Greek letters , substitute 2,i and -i , we get ,
Now multiply (x-i) and (x+i ) using the identity (a+b)(a-b)=a² - b² , we have ,
Simplify using i = √-1 ,
Multiply by distribution ,
Simplify by opening the brackets ,
Rearrange ,

Answer:
and? obviously bc 3 isnt a even number so then the answer wont be even
The sum of the interior angles of a hexagon is equal to sum of six consecutive numbers. Hence let the smallest consecutive number be x. Then other five numbers are x+1, x+2, x+3,x+4 and x+5. Hence the measure of the smallest angle is 117.5 cm.
Answer:
A
Step-by-step explanation:
Just plug numbers and it will give you graph attributes
If the line is perpendicular to x = 4, then that means the answer should be y = some number
and since we have the equation going through point (5,7), we look at the y-value since our equation is y=some number and replace the y-value into that equation.
So the correct answer is C. y = 7
Hope that helps :)
