C(h,k) radius(r)
C(2,-3) r=4
(x-h)^2 + (y-k)^2 = r^2
(x-2)^2 + (y--3)^2 = 4^2
(x-2)^2 + (y+3)^2 = 16
therefore, the answer is D
Expression
(5+3)+(5x2)=p
Solution
18
(Step-by-Step)
In this expression we simply have to use basic PEMDAS (Parenthesis Equation Multiplication Division Addition Subtraction) Order.
We start by working out the parenthesis
5 + 3 and 5 x 2
First let's work out our metal and wood paperweights
5+3=8
Simple enough, we have 8 metal AND wood paperweights
Now we have to work out our glass paperweights.
We have twice as many glass as we do metal PW's meaning we need to multiply the 5 metal paperweights by 2
5x2=10
This simplifies and boils our equation down to
8+10
simply solve and add the two and you have your answer

Answer:
The answer is 12.
12 is not a perfect square like the others.
The derivative would be f'(x)= -9
