Answer: 3x^4 +x^3 -2x^2 +3x +2
Step-by-step explanation:
(3x^4 - 2x^3 + 4x -2) + (3x^3 - 2x^2 - x +4)
There are no like terms for 3x^4, so leave it alone.
-2x^3 + 3x^3 = 1x^3
No like terms for -2x^2
4x - x = 3x
-2 + 4 = 2
Answer? 3x^4 +x^3 -2x^2 +3x +2
(Please mark brainliest! :) )
-9 because a negative plus a negative is a negative so -5+-4 or -5-4 is -9

Answer:
Step-by-step explanation:
1. Write your formula
2. Plug it in
3. Solve
these steps will help you out with all of your surface area problems.
Like this
Since it is a <u>diameter</u> you have to divide the diameter by 2. That will get you your radius. Then you write your formula for a cylinder. Your formula is...
V = Bh (Pie is also known as 3.14)
your big (B) is (pie times r squared) Then you add your height.
so your formula will look like this...
V = pie times r squared...
the full formula will be...
V = (3.14) times (2.5 squared) times the height which in this case is (12)
everything together will be...
V = (3.14) (2.5^2) (12)
all you have to do is multiply all of that and you will get your answer.
The answer is...
V = 236 inches ^2 (Just a tip, the ^ sign means to the power of)
