Assuming you want to solve for x the result can vary. The result can be shown in multiple forms. Hope this helps!
Inequality Form:
−5≤x≤2
Interval Notation:
[−5,2]
q = 10p because all of them are multiplied by ten
Given problem;
A = 4 π R²
To solve for R, we have to make it the subject of the expression.
Since
A = 4 π R² , follow these steps to find R;
Multiply both sides by
A x
=
x 4 π R²
= R²
Then find the square root of both sides
√R² =
R = 
The solution is 
I hope that A. Is the answer

When you're multiplying by a power of 10 such as 100, the decimal point moves two places to the right. Note that this corresponds with the number of zeroes in 100. Of course our number is going to get bigger, not smaller, which means we'd have to be going right. If we multiplied by something like 0.001, we'd also be going two places, just going smaller and to the left.
