Module 6 Polynomial the question is in the picture. Alana completed a problem where she had to find the sum of the polynomials (
3x^2+8x-4) and (-8x^3-3x+4). Her answer is 0. Complete the explanation and correct her mistake. When graphed, how many times does the sum change directions??
A rectangular plot of land has a length of (2x^2+5x-20) and a width of (3x+4). What is the polynomial representing the area of the plot of land? Explain how you got your answer. Below.

Answer:
Step-by-step explanation:
The funtion is:
C(p)= 3(p)+1.07 (1)
where: 3 is the package cost, p is the number of packages and 1.07 is the taxes
the cost could be equal or less than the gift card value so:
C (2)
Replace 2 en 1
x 1.07
3(p)
14.02\\\\p\leq \frac{14.02}{3} \\\\p\leq 4.67[/tex]
It´s important to aprox the quantity to the minimum value so I can buy 4 packages
The reasonable domain is for all R because any number is a possible value of the independent variable
