Answer:
Step-by-step explanation:
f(x) -h(x) = x³ + 2x² -7x - 8 - [4x² - x - 15 ]
= x³ + 2x² - 7x - 8 - 4x² + x + 15
= x³ + 2x² - 4x² - 7x + x - 8 + 15
= x³ - 2x² - 6x + 7

<h3>
How to analysis the perimeter formula of a rectangle inside a parabola</h3>
a) The perimeter of a rectangle (
) is the sum of the lengths of its four sides:
(1)
If we know that
and
, then the perimeter of the rectangle is represented by the following formula:


The <em>perimeter</em> function of the rectangle is
. 
b) The domain of the function is the set of values of
associated to the function. After a quick inspection, we find that the domain of the <em>perimeter </em>function is
. 
<h3>Remark</h3>
The statement is incomplete and poorly formatted. The correct form is described below:
<em>As shown at the right, rectangle ABCD has vertices C and D on the x-axis and vertices A and B on the part of the parabola </em>
<em> that is above the x-axis. a) Express the perimeter </em>
<em> of the rectangle as a function of the x-coordinate of A. b) What is the domain of the perimeter function?</em>

Answer: Correct choice is B.
Answer:
The least common denominator would be 42.
Step-by-step explanation:
6 and 7 don't share any common multiples with any other number besides 6 or 7.
6 * 7 = 42
