Answer:
2000 people
Step-by-step explanation:
The area of the gym is the width times length:
A = wl
A = (50 ft) (100 ft)
A = 5000 ft²
Write a proportion:
1 person / 2.5 ft² = x / 5000 ft²
x = 2000 people
X + x + 1 + x + 2 = 12
x + x + x + 3 = 12
subtract 3 for each side
x + x + x = 9
3x = 9
divide 3 from each side
x = 3
Small side 3 feet
Middle side 4 feet
Long side 5 feet
The answer is (-8z)^2= 16z^2
Considering the conversion from exponent to radical, the equation that justifies why the expression
is correct is.

<h3>How is the conversion from exponent to radical realized?</h3>
The conversion of rational exponents to radical notation is modeled by:
![a^{\frac{n}{m}} = \sqrt[m]{a^n}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bn%7D%7Bm%7D%7D%20%3D%20%5Csqrt%5Bm%5D%7Ba%5En%7D)
In this problem, the expression is:
![9^{\frac{1}{3}} = \sqrt[3]{9}](https://tex.z-dn.net/?f=9%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%20%3D%20%5Csqrt%5B3%5D%7B9%7D)
And the equation that shows that this is correct is:
