Hi there!
Let's solve this problem step by step!

To find f(3) we must substitute x = 3 into the formula.

Now we use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.
Work out the exponents inside the parenthesis first.

And finally multiply.

Hence, the answer is D. 64.

32 homes. divide 96 by 3 because the 96 homes each took 3 kittens
You can't know with only volume. Sorry.
Left side = 170-58 =121'
Bottom side = 96-4 =92'
Now let's calculate the upper oblique (slantwise) side by Pythagoras
oblique² = 92²+28² = 9248 & oblique =√9248 = 96.167'
The perimeter of the backyards = 96.167+93+92+121 = 402.167 ft
