The answer would be choice A. 2
<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.
Answer:

Step-by-step explanation:
We have a composite figure, therefore the volume of the figure will be the sum of the volume of both figures.
The volume of the rectangular prism is the product of its length by its width by its height

The volume of the triangular prism is

Where
is the area of the triangular base and l is the length


Finally


X^2 + 2x - 35
(a x b) = -35
(a + b) = 2
(7 x -5) = -35
(7 + -5) = 2
Plug them in:
x^2 - 5x + 7x -35
x(x - 5) + 7(x - 5)
Therefore, you can conclude that our final answer is...
(x + 7)(x - 5)
