Ответ:
Part A
The area is 20x5+16x4−26x3+22x2+32x−24 sqaure units
Part B
Yes the answer is polynomial
Part C
The degree is 5
Step-by-step explanation:Part AThe solution is given in the attached figure
Part BIn 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.
Part CThe 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.
