Answer:
(4x - 5)(5x - 4)
Step-by-step explanation:
20x² - 41x + 20
41 ± √1681 - 4(400) / 40
41 ± 9 / 40
5/4 or 4/5
Now using the zeros,
(x - 5/4) (x - 4/5)
(4x - 5)(5x - 4)
Using proportions, it is found that the interval for the number of times Elliot must visit his parents is [14, 41].
---------------------
- The interval is found using proportions, by a rule of three.
- In each visit to his parents, Elliot flies 350 miles.
- To qualify for Gold status, he must fly at least 4900 miles. How many trips are this:
1 trip - 350 miles
x trips - 4900 miles
Applying cross multiplication:
![350x = 4900](https://tex.z-dn.net/?f=350x%20%3D%204900)
![x = \frac{4900}{350}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B4900%7D%7B350%7D)
![x = 14](https://tex.z-dn.net/?f=x%20%3D%2014)
He must visit his parents at least 14 times.
---------------------
- Also less than 14700 miles, how many trips are this?
1 trip - 350 miles
x trips - 14700 miles
![350x = 14700](https://tex.z-dn.net/?f=350x%20%3D%2014700)
![x = \frac{14700}{350}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B14700%7D%7B350%7D)
![x = 42](https://tex.z-dn.net/?f=x%20%3D%2042)
Less than 42 trips, thus at most 41 times.
The interval is [14, 41].

Answer:
prism
Step-by-step explanation:
The figure will not be a cube, because a cube does not have any triangular faces.
The figure will not be a pyramid, because a pyramid has a triangular face for each edge of the base.
The figure will not be a triangle, because a triangle is a plane figure.
The figure will be a triangular <em>prism</em>: a figure with parallel bases, each having 3 edges, and a rectangular face associated with each of those edges.
