Answer:
C
Step-by-step explanation:
We are given that
DCB and
CDA are supplementary.
We have to identify the parallel segments if
DCB and
CDA are supplementary.
Supplementary angles: If the angles are supplementary then the sum of two angles is 180 degrees.
Therefore,

Therefore, angle DCB and angle CDA are interior angles .
Because CA is a transversal line and sum of interior angles is 180 degrees.
When the sum of interior angles formed between two lines and on same side of transversal line is 180 degrees. Then the lines are parallel.
Therefore, angle DCB and angle CDA are formed between line AD and BC.
Hence, AD is parallel to BC.
Option C is correct.
Perimeter:

Area:

Step-by-step explanation:
Perimeter of a rectangle : P= 2( L + w)
in this case it would be 2(y+6) + 2(2y)
= 2y+12 + 4y
simplified to 6y +12
Area of a rectangle : A= LW
=(y+6)(2y)
We foil and get

For this case we have the following scenario:
Carlos enrolled in a gym to play sports. Carlos pays a fee for the registration and must pay 1 dollar for each day he trains in the gym. Write an equation that models the problem.
The equation that models the problem is:
y = x + 1.
The slope of the line is 1 and represents the payment of 1 dollar for each day trained.
The intersection with the y axis is 1 and represents the payment of 1 dollar for the initial inscription.
