I don't know what is between f(x) and g(x), so (for now) there are two posible answers:
1.

- function multiplication:

2.

- function composition:
Answer:
A
Step-by-step explanation:
Because a^2+b^2=c^2 in a right triangle by Pythagorean's Theorem. So, the only one that works is 3^2+4^2=5^2 because 9+16=25.
Since the shower block is in the form of a rectangle. The shower block has an area of 144
. It has a length of 24m. We need to calculate the width of the shower block.
Area of rectangular shower block = length
width
144
= 24 m
width
width = 
width = 6m
So, the width of the shower block is 6 meters.
