To find the volume of a cylinder it's
πr² x height.
So π x 10² x 10 would be the equation.
I would do it but I don't have a scientific calculator on me.
Answer:
Simplify 3(x+1)−5.
3x−2=3x−2
Move all terms containing x to the left side of the equation.
−2=−2 Since −2=−2 , the equation will always be true for any value of x
All real numbers
The result can be shown in multiple forms.
All real numbers

Step-by-step explanation:
Answer:
The regular price was $30.
Step-by-step explanation:
The bookstore sells used books at 40% discount off the price of new books. This means, after the discount, the price of a used book will be 100% - 40% = 60% of the original price.
Now, if the price of the used book is $18, we know that is is 60% of the price of the book when it was new.
Let us call
, the price of the book when it was new, then we know that
<em>(this says that 60% of the original price is $18.</em><em>)</em>
We solve for
and get
![x=\frac{18}{0.6} =30.](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B18%7D%7B0.6%7D%20%3D30.)
The price of the book was $30 when it was new.
Log2 (x - 6)(x - 4) = log2 x
(x-6)(x-4) = x
x^2 - 10x + 24 - x = 0
x^2 - 11x + 24 = 0
(x-3)(x-8) = 0
answer is 8
