Answer:
Option C. 4(20-16y): Each side measures 20-16y units.
Step-by-step explanation:
we know that
The perimeter of a square is equal to

where
b is the length side of the square
we have

substitute the given value in the formula

solve for b
Divide by 4 both sides

Rewrite the expression

<em>Alternative Method</em>
we have

Factor 4

so
Each side measures (20-16y) units.
Multiply both sides by three to get 2x=30
Then divide both sides by 2 to get x=15
Answer:
exactly 12:00 midnight on a 24hour clock is represented as 00:00
Function transformation involves changing the form of a function
The function g(x) is 
The function is given as:

g(x) is an exponential function that passes through points (-2,2) and (-1,4).
An exponential function is represented as:

At point (-2,2), we have:

At point (-1,4), we have:

Divide both equations

Simplify

Apply law of indices


Rewrite as:

Substitute 2 for b in 

This gives

Multiply both sides by 4

Substitute 8 for (a) and 2 for (b) in 

Express as a function

Hence, the function g(x) is
