Answer:
B.) Associative Property of Addition 
Step-by-step explanation:
This is because none of the numbers change places the only things that move are the parenthesis which correspond with the associative property.

Answer:
The frequency of the given sinusoidal graph is 4.
Step-by-step explanation:
The frequency of a sinusoidal graph is the number of cycles it completes in the interval 0 to 2π radians.
From the given sinusoidal graph it is noticed that the the graph complete its one cycle in the interval 0 to  .
.
If the complete its one cycle in  , then the number of cycles completed by the graph in the inteval 0 to 2π is
, then the number of cycles completed by the graph in the inteval 0 to 2π is



Therefore the frequency of the given sinusoidal graph is 4.

Answer:
Step-by-step explanation:
Bisection is the division of a line or an angle into two equal halves. It means that a bisector is a line that divides an angle or another line into two equal halves. Therefore,
Line BE divides angle ABC into two equal halves. This means that
Angle ABC/2 = angle ABE = angle EBC
Therefore,.
2x + 20 = 4x - 6
4x - 2x = 20 + 6
2x = 26
x = 26/2 = 13
Therefore, 
Angle ABE = 2 × 13 + 20
 = 46 degrees
