25 x 13 = 325
20x 8 = 160
325-160 = 165 square feet
answer is A
This is simple simplifying. If you need an explanation dm me.
here is the answer
x=-5
Given:
f(x) is an exponential function.


To find:
The value of f(0.5), to the nearest hundredth.
Solution:
The general exponential function is

For, x=-0.5,

...(i)
For, x=1.5,

...(ii)
Divide (ii) by (i).


Taking square root on both sides, we get


Putting b=0.882 in (i), we get




Now, the required function is

Putting x=0.5, we get



Therefore, the value of f(0.5) is 23.81.
