Answer:

A, D

Step-by-step explanation:

When we multiply the fractions, we can get:

$\frac{1}{5^{4} }$

This is also equivalent to:

$5^{-4}$

When looking at the answer choices, the only ones that equal $5^{-4}$ are A and D because:

$(5^{-2})^{2} =5^{-4}$

$5^{2}*5^{-6} = 5^{-4}$

ozzi

Answer:

$\boxed{Side \ Length \ of \ hot \ tub = 4.8\ ft.}$

Step-by-step explanation:

Scale Factor = 5

Also,

AB = BC = CD = DA = 24/5 = 4.8 ft.
