Answer:

49n² - 70n + 25

Step-by-step explanation:

Area of a square = s²

Where,

s = side length = 7n - 5

Area of the square = (7n - 5)²

= (7n - 5)(7n - 5)

= 7n(7n - 5) -5(7n - 5)

= 49n² - 35n - 35n + 25 (distributive property of equality)

Add like terms

Area = 49n² - 70n + 25

Working independently at the same constant rate, 9 machines can fill an order in 20 hours. How many of these machines, working i
Katena32 [7]

Answer: 4 machines

Step-by-step explanation:

In the given situation, the number of machines is inversely proportional to the time taken by them.

Given : 9 machines can fill an order in 20 hours.

Let n be the number of machines required to fill the same order in 45 hours.

Then , we have the following inverse variation equation:-

n\times 45=9\times20\\\\\Rightarrow\ n=\dfrac{9\times20}{45}=4

Hence, the 4 machines would be needed to fill the same order in 45 hours.
