A)Theorem. every theorem can be proved.
Answer:
see the explanation
Step-by-step explanation:
we know that
The circumference of a circle is equal to

where
D is the diameter
In this problem we have


substitute and solve for D



we know that
The length of the row of quarters is equal to multiply the diameter of the quarter by the number of quarters in the row
so
For 4 quarters in the row, the length is equal to --> 
For 6 quarters in the row, the length is equal to --> 
For 12 quarters in the row, the length is equal to -> 
System b should be (-3,2)!
It is the last one because if you go 3 left you have to change the sign to a positive (but it is still a negative) and the 2 remain the same sign so it’s h(x-3)-2
