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 .
Answer
Step-by-step explanation:
first off rt(2x^5) can be simplified as x^2 rt(2x) because we can break up x^5 into x^4 * x. x^4 is a perfect square so factor out a x^2.
the denominator can be written as
since the factors of 18 involve a perfect square of 9. 9*2 is 18 so factor out a 3.
the whole fraction :
cancel out the and you are left with
