PLEASE. MARK ME AS BRAINLIEST ANSWER.
Wouldnt it be 21 idk dont pay attention to me lol
Perimeter is the sum of all the sides of the shape
do you know the length of each side of the parallelogram?
Answer:
The zeros of the given polynomial function are
2,2,
Step-by-step explanation:
Given polynomial is 
To find the zeros equate the given polynomial to zero
ie., P(x)=0

By using synthetic division we can solve the polynomial:
2_| 1 -4 -1 20 -20
0 2 -4 -10 20
_____________________
1 -2 -5 10 |_0
Therefore x-2=0
x=2 is a zero of P(x)
Now we can write the cubic equation as below:

Again using synthetic division
2_| 1 -2 -5 10
0 2 0 -10
______________
1 0 -5 |_0
Therefore x-2=0
x=2 is also a zero of P(x).
Now we have 


is a zero of P(x)
Therefore the zeros are 2,2,
The answer is B
hope this helps
