∠ACB = ∠ABC = 360°/8 = 45°
_____
∠ABC is an external angle of the octagon. Since it is equiangular, all external angles are equal. The sum of external angles of a convex polygon is always 360°, so one of 8 of those angles will be 360°/8 = 45°.

x + 3y − y + 3x + 2(2 + 4 + y)
= 4x + 2y+ 12 + 2y
= 4x + 4y + 12
answer
</span>B: 4x+4y+12
