12ft = 4 posts
4 x 4
=16 - 4
= 12
There is 4 post on each side but there is an overlap so you must take off 4 so there is no overlap
Therefore there are 12 posts
A. 4*1 - 3*2 = 4 - 6 = -2 (X
B. 4*4 - 3*2 = 16 - 6 = 10 (O
C. 4*7 - 3*6 = 28 - 18 = 10 (O
D. 4*4 - 3*(-3) = 16 + 9 = 25 (X
so the answers are B and C
