Answer:
x²-6x+y²-4y=-4
Step-by-step explanation:
We know the circle equation stands like this:
(x-a)² + (y-b)² = R²
and (a,b) is center
and R stands for Radius
so in this case:
center = (3,2)
R = 3
So
(x-3)² + (y-2)² = 9
x²-6x+9 + y²-4y+4=9
x²-6x+y²-4y=-4
we have
<u>Pieces of mail delivered in December by the US postal service</u>

<u>Pieces of mail delivered in January by the US postal service</u>

To find the total mail delivered for these two months, sum the two quantities
so

therefore
the correct solution is

Let the number of hours she works be x
2x+15 15 more than twice the
3x-15 15 less than 3 times the hours she worked
2x+15=3x-15
3x-2x= 30
x= 30
the number of hours she worked is 30
