Answer:
Step-by-step explanation:
∠CBA + ∠ABD = 180 {linear pair}
2x - 6 + x +1 = 180
3x -5 = 180
3x = 180 +5
3x = 185
x = 185/3
x = 61 2/3

Answer:
A) -20
Step-by-step explanation:
distribute the 4y and the -4 to the parentheses
16y^2 -16y+16y-20-16y^2
combine like terms
16y^2-16y^2=0
-16y+16y=0
-20
