Well 20% is 1/5 of 100% so just multiply 7.5 by 5.
The answer is 37.5
<h2>
Answer:</h2>
Part A
<u>The area is 20x5+16x4−26x3+22x2+32x−24 sqaure units</u>
Part B
<u>Yes the answer is polynomial</u>
Part C
<u>The degree is 5</u>
<h2>
Step-by-step explanation:</h2><h3>Part A</h3>
The solution is given in the attached figure
<h3>Part B</h3>
In mathematics, a polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. So the answer is a polynomial in our case.
<h3>Part C</h3>
The degree of a polynomial is the highest degree of its individual terms with non-zero coefficients. The degree of an expression is the sum of the exponents of the variables that appear in the polynomial, and thus is a non-negative integer. In our case the degree of the polynomial is 5.
Given:
The expression is

To find:
The expression which is equivalent to the given expression.
Solution:
We have,

We know that,

Using this formula, the given expression can be written as



Therefore, the given expression is equivalent to 1.
You can drag in the first empty box ∡3 and get ∡2≅∡3.
In the second box you can drag '' definition of angle bisector ''.
In the third empy box you can drag ∡1 and get ∡1≅∡3.
At last empy box you can drag ''transitive property of congruence''
Good luck!!!
