Step-by-step explanation:

Step 2: Combine like terms

3a² + ab + 3ac + 2b² - 2bc

Step 3: Distribute again

-4ac + 4bc + 4c² - (3a² +ab + 3ac + 2b² -2bc)

Step 4: Combine like terms again

-3a² - ab - 7ac - 2b² + 6bc + 4c²

And you have your final answer.

Ian is going to water his plants is it reasonable to say he will fill the watering can with 3 liters of water explain
sveta [45]
This is possible for a smaller watering can. 3 liters is about 3/4 of a gallon (imagine a jug of milk).

It is equivalent to 3000 ml, which would also be 100 ounces of water.(5 -20 oz bottles of water).

What is the perimeter of 2m 10cm by 45 cm
qwelly [4]
I believe it is 510 cm because a meter equals 100 cm so 210 cm times 2 equals 410 cm then multiply 45 times 2 and get 90 cm then add 410 plus 90 and get 510 cm.
