Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression

Apply exponent rule: 
∵ 

Factor out common term 2y

We know that the Binomial is an expression that consists of two terms. Thus,
(4x²y²- 9) represents the binomial factor of 
We can further simplify by Factoring 4x²y² - 9: (2xy + 3) (2xy - 3)

Here:
(2xy + 3) and (2xy -3) are the binomial factors of
as each of them consists of two terms.
Answer: C. 4 hours
Explanation: You first measure how long 1/5 of an hour is in which is 12 minutes. You then multiply 12 by 20 because it takes 12 minutes to get 1/20 of the lawn watered. Your answer now should be 240. Finally, divide that number by 60 because you are measuring time in hours. Your final answer should be 4 hours.
The answer is 17.5!! goodluck
