Answer:
If your trying to simplify then your answer would be 
Given,
∠AOE = 30°
∠DOB = 40°
So, ∠EOD = 180 - (30+40) [angles on a straight line]
= 180 - 70
= 110
∠EOD = ∠COF [ vertically opposite angle]
∴ ∠COF = 110°
Answer:
b: -2y and 4y
Step-by-step explanation:
The answer is option B
-2y and 4y are like terms because they have the same algebraic alphabet at the back of their coefficients.
