First, we should add 1 to both sides to isolate the variable:
3x = 12
Now that x is isolated, we divide by 3:
x = 4
Answer:

Step-by-step explanation:
● formulas of valume = πr²h
- 22/7×12×12×38•4 ft
- 3•14×144×38•4 ft
- 452•16×38•4 ft
- 17362•944 ft³
● now nearest to the number
- 17262•944 ft³ nearest tenth is 17360ft³.

Answer:
Option C.
Step-by-step explanation:
We start with the expression:

where y > 0. (this allow us to have y inside a square root, so we don't mess with complex numbers)
We want to find the equivalent expression to this one.
Here, we can do the next two simplifications:

And:

If we apply these two to our initial expression, we can rewrite it as:


Here we can use the second simplification again, to rewrite:

So, concluding, we have:

Then the correct option is C.
