The formula of the volume of a cylinder:

We have:

and

substitute:
Answer: The area of a base of the cylinder is equal 45 dm².
(-7,8)
Simplifying 2(x+7)^2+8
Will give you the image results
You must graph the formula and you’ll get -7,8 (using desmos helps)
How many pints are in a tank? If you know that you can answer the question. He drinks 120 pints in 30 days because 30 x 4 = 120. To get the answer you just divide 120 by the number of pints in a tank and you have your answer.
Lets say each jersey cost x,
then 12 jerseys will cost 12x
Total costs will then be 12x + 3, 12x of costs plus $3 of shipping
We already know that the total cost is $99
so 12x + 3 = 99
Now isolate x by subtracting 3 from both sides
12x 3 - 3 = 99 - 3
12x = 96
Now divide both sides by 12 to find x
12/12x = 96/12
x = 8
Each jersey cost $8
Answer: You can use the equation 12x + 3 = 99 to find the cost of each jersey
Hope it helps :)
