For this case we observe that the lines AB (red) and CD (purple) are cut at one point.
We observe that the slopes of both lines are different (they are not reciprocal opposites).
Therefore, the lines are not perpendicular.
Answer:
AB and CD are intersecting lines but are not perpendicular.

Answer:
28 ft²
Step-by-step explanation:
The area of a circle is , where r = radius. To find the radius, we split the diameter in half.
- 6/2 = 3
- Thus, the radius is 3.
Now, let's find the area of the circle and approximate pi to 3.14.
- 28.26 ≈ 28 ft²
Therefore, the answer is 28 ft².
Answer:
B. Yes, they both mean the same thing. They can also both be represented by the expression y - 6.
