The first 5 figures in a pattern are shown. If the patterncontinues, which expression can be used to find the number of circles to make up Figure n? f. n^2+ 2n
h. 2n^2+ 1
g. n^2+ 2
j. 2n^2+n

F.

the corect answer for this question

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

to determine the unit cost your would divide the total cost by the number sold.
