In terms of X then x would be equal to -2
No B
lets say W is 5
C is saying 4x5+6 right?
so all 4 side are 5 and plus a random six
W is only equal to 2 sides so C and D are gone
A. 2 x 5 + 6 is saying
2 sides are 5 + 6 and then a missing side
but B is 2 x 5 + 12
B could also say 2 x 5 + 2 x 6
2 sides are 5 and then 6 side are 5
Your answer is B
