Answer:
I'm pretty sure it's both, but I can see this is a summative exam/test so I'm really sorry if it's wrong.
(y^-5) / (y^-2)
Flip fraction and get rid of the negative from the exponents (you can do that!)
(y^2) / (y^5)
(y * y) / (y * y * y * y * y)
Cancel y's
1 / (y * y * y)
1 / (y^3)
That's your answer.
Have an awesome day! :)
Answer:

Step-by-step explanation:

1. set the equation for the area of each shape equal to each other
2. simplify each side until you get 
3. subtract 16 from both sides which will give you 
4. subtract 3x from both sides which will give you the value of x. 
5. check that
is correct by plugging it into the equations
triangle:

rectangle:

the areas are the same
Answer:

Step-by-step explanation:
If the corner of your porch is the origin
- 4 ft to the left, x=-4
- 5 ft in front, y=5
The tree's location is at (-4,5).
- A circular fence 3 ft in radius has its center at the tree(-4,5).
We want to determine the equation of a circle with center (-4,5) and radius 3 ft.
The equation of a circle center (h,k) with a radius of r is given as:

(h,k)=(-4,5), r=3
The equation formed by the fence therefore is:
