Answer:
Step-by-step explanation:
Since 15 liters of water flow through a water pipe and enter a tank within 4.5 minutes, the same amount of water would flow through a similar pipe at the same time. Therefore, if two similar water pipes are used, the volume of water that would flow into the tank in 4.5 minutes is 15 × 2 = 30 liters
Therefore, the time it will take to pump 727.5 liters of water into a water tank using 2 similar water pipes is
(727.5 × 4.5)/30 = 109.125 minutes
In word form is: three hundred twenty-four thousand, nine hundred four.
Answer:
5x^2+x-4
Step-by-step explanation:
Multiply 5x into (x+1)
to get 5x^2+5x
Multiply -4 into (x+1)
to get -4x-4
Combine like terms
5x^2+5x-4x-4
Answer:
5x^2+x-4
