Answer:
a) The polynomial is equivalent to
, and the side length of the playground is
feet.
b) The perimeter of the playground, measured in feet, is
.
Step-by-step explanation:
a) By Geometry, we know that area of the square is equal to the square of the side length. If
is the area of the square, then must be a perfect square trinomial, that is:
(1)
Then, we must observe the following properties:
(2)

(3)

Therefore, the polynomial is equivalent to
, and the side length of the playground is
feet.
b) The perimeter of a square equals four times the side length. That is:

The perimeter of the playground, measured in feet, is
.
Y+60=180 then y=120
5z-100=60 then 5z=160 then z=32
Answer 4
6 goes into 24 4 times and since both the top and bottom are negative the answer is positive
X=50
