Year 3 = 2s
Year 2 = 3 + x
Year 1 = x
s = second year
x = first year
2s = 26
s = 13
The second year they made 13 million
13 - 3 = 10
x = 10
They made 10 million the first year.
If you picture a cylinder rolled out flat. there would be two circles for top and bottom and then a rectangle for the side. The rectangle would have width equal to height and length equal to circumference.
So then the areas of the pieces are added together to get total surface area.
= 2pi(3x-2)^2 + 2pi(3x-2)(x+3)
and you can simplify this is you want by multiplying through and combining like terms.
= 2pi(12x^2 - 5x -2)
or factor more to simplify the solution.
= 2pi(3x-2)(3x-2+x+3)
= 2pi(3x-2)(4x+1)
Answer:
2x^3+3x^2-50x-75
Step-by-step explanation:
(x+5)(x-5)=x^2-25
(x^2-25)(2x+3)=2x^3+3x^2-50x-75
Can I have brainliest!
Answer:
The correct answer here is A. x = 17.
How I found this out:
3x + 3 and 5x - 7 are going to be different solutions in the end.
I did the process of elimination.
First, I subsituted, 17 for x. 3 X 17 + 3 = 54. 5 X 17 - 7 = 78.
I then took 180 - 54 - 48 = 78 and 180 - 78 - 48 = 54, just to make sure they are positive numbers and not negative.
Since they work out, I chose this as my correct answer to your question.
Step-by-step explanation:
Hope this helps! :)
I tried my best so I'm it's wrong.
We have point
, so first calculate
. There will be:
Now, we can write the equation of the normal line as:
Normal line (and every line) crosses x-axis when y = 0, so coordinates of A:
