Answer:
A). Scale factor = 
B). Length of the unknown side = 2.75 feet
Step-by-step explanation:
Part A
Since, the large rectangle was scaled by a scale factor 'k' to form the smaller rectangle,
Scale factor = 
= 
= 
= 
Part B
Scale factor = 

Therefore, side length of the unknown side =
= 2.75 feet
The slope is 9/3 which can be simplified into 3/1
I got 6 units^2. So the answer is the second choice. ab/2 = 3*4/2 = 6.
In this specific case, the <em>initial term</em> (a) is 5 and the <em>common ratio</em> (r) is -2
Henceforth, after determining what a and r are, we use the formula for the <em>nth term</em>. Which is:

Therefore, the 14th term is :
