Hello!
Robin can clean 72 rooms in 6 days. How many rooms can Robin clean in 9 days?
We have a proportional magnitude (directly proportional), if we increase the number of days for cleaning, obviously we will have more rooms cleaned, then:
clean rooms __________ days
72 ----------------------------------- 6
y ------------------------------------- 9
multiply the means by the extremes
Answer:
108 clean rooms in 9 days

Answer:
The answer is D.
Step-by-step explanation:
It is given that Gabriella swims 2 laps for 1 minute. So in order to find how many minutes did he swim for each lap, you have to divide it by 2 :
2 laps = 1 minute
2 laps ÷ 2 = 1 minute ÷ 2
1 lap = 1/2 minute
= 30 seconds
Test :
Gabriella swim 1/2 min per lap. So if he swim 2 laps, you have to multiply it by 2 :
1/2 × 2 = 1 minute
The correct answer is the first option, which is:
5(x+3)(x-3)
The explanation is shown below:
1. To solve the problem shown in the figure attached, and factor the given equation, you must apply the following proccedure:
1.You have the following equation given in the problem: 5x^2-45. As you can see, it is a quadratic equation.
2. When you factor it, you obtain:
5(x^2-9)
5(x+3)(x-3)
3. Therefore, the answer is the optiones mentioned before.
