not enough to figure out :/
Answer:
I believe the answer you are looking for is C
Step-by-step explanation:
Isn't it 5? x=5 cause the model's height is 4 less than the width so like if the actual width is 9 than the height is 4 smaller
a geometric sequence is a bunch of numbers where you can get from a number to the next number by multiplying the previous number by a certain number
might be confusing so here's an example
1,2,4,8,16
each term is multiplied by 2 to get next term, that number that each term is multiplied by is called the common ratio
formula for geometric sequence is

where
is nth term
is first term
r is teh common ratio
n=which term
in our example
1,3, 9, 27, 81
each term is being multiplied by 3 so it is a geometric sequence and thus r=3
also first term is 1 so 
so the formula is
or in function notation
