The standard equation of a circle:

We have the center (-4, 0) → h = -4 and k = 0, and the radius r= 3. Substitute:

Answer:
18
Step-by-step explanation:
Let the unknown number be = x
Then,
x + 16 = 34
=> x = 34 - 16
=> x = 18 (Ans)
We are given (xy)^(-3).
This leads to 1/(xy)^3.
You see, going from the top to the bottom alters the sign of the exponent to its opposite.
ANSWER: 1/(x^3•y^3)

40 is the correct answer. Hope this helps :)
Since division is the opposite of multiplication, you can turn this division problem into a multiplication problem by multiplying the top fraction by the reciprocal of the bottom.
