Answer:
A
Step-by-step explanation:
If x is the number of shirts you multiy by 15. 2.25 is the additional cost
Answer:
The required recursive formula is:

Step-by-step explanation:
We are given a geometric sequence as:
6,-18,54,-162,.....
Clearly after looking at different terms of the sequence we could observe that the sequence is an geometric progression (G.P.) with common ratio= -3 denoted by r.
Let
represents the nth term of the sequence.
This means that:

As the common ratio is -3.
so,

Hence, the required recursive formula for the geometric sequence is:

2/3 is the simplified form of 18/27
If you are talking about radius of circle it is 2463
Well you have to find the lest common factor
8 times 6
6 times 8
They both equal 48 so it would be the vise versa
