Answer:
17.9 m²
Step-by-step explanation:
The area of the deck is the difference between the area of the square and the area of the circular hot tub.
__
<h3>square area</h3>The area of the square is given by the formula ...
A = s² . . . . where s is the side length
For a side length of 5 m, the area is ...
A = (5 m)² = 25 m²
<h3>circle area</h3>The area of a circle is found from the formula ...
A = (π/4)d² . . . . where d is the diameter
For a diameter of 3 m, the area is ...
A = (π/4)(3 m)² = 9/4π m² ≈ 7.069 m²
<h3>deck area</h3>The area of the deck is the difference between the square area and the circle area:
deck area = 25 m² -7.069 m² ≈ 17.9 m²
The area of the deck surrounding the hot tub is about 17.9 m².

Answer:
" is irrational for every nonzero integer x"
Step-by-step explanation:
The original statement is
" is rational for some nonzero integer x."
The negation is technically:
"It is NOT true that is rational for some nonzero integer x."
So it's expressing that it's false that can be rational for some nonzero integer x.
This just means that is always irrational when x is a nonzero integer.
Which can be worded as
" is irrational for every nonzero integer x"
