So this means W(-3x) = 3x. So it's equal to 3(-3x), which simplifies to be -9x. Whenever you have a function, it looks like f(x). f doesn't have to be the letter, it can be a, b, c, or like in this case, W. It just means the output of what W(x) is if x equals the number in the parentheses, which is -3x in this case.
Answer:
The area of the circle is 314 in^2.
Step-by-step explanation:
10 inches is the radius.
The formula for the area of a circle is pi times radius squared.
So your equation would be: 
10^2 = 100
Then you do 
or 3.14 times 10 = 314.1592654 or just 314.
