Answer: -6
Step-by-step explanation:
From the question, Elsa pumped 18 gallons of water out of her pool and this was done over a period of 3 minutes at a constant rate. Since it is done at a content rate, to get the change in the amount of water in the pool each minute, we divide 18 gallons by 3. This can be written mathematically as:
= 18 gallons ÷ 3
= 6 gallons
Change = -6
The change in the amount of water in the pool each minute will be -6gallons
I cannot help you with this answer just guess slap and guess a
9/4

Answer:
22, I think
Step-by-step explanation:
You count all the squares on all of the faces.
So you count the two on the top and double it for the bottom, so four
Then, on the sides you have three so you double that and get six
Next, you double the six squares on the other side and get twelve.
Lastly, you add them up!
4 + 6 + 12
Hope this helps!
