Answer:
Perimeter of quadrilateral
will be 
Step-by-step explanation:
Given quadrilateral
is a reflection of quadrilateral
over the line
.
So, all the corresponding sides of both the quadrilateral should be equal.
Also, we can see from the diagram that 
As both image are reflection of same scale we can add corresponding sides.
So, the perimeter of
will be

And we have 
Now, perimeter of
will be 
Perimeter of quadrilateral
is

Answer:
The degree of the polynomial is 3
Step-by-step explanation:
Given:

To Find:
The degree of the polynomial= ?
Solution:
The degree of the polynomial is the value of the greatest exponent of any expression (except the constant ) in the polynomial. To find the degree all that you have to do is find the largest exponent in the polynomial
Here in the given polynomial

The terms are



The term
has the largest exponent of 3
Note: The degree of the polynomial does not depend on coefficients of the terms
