Step-by-step explanation:
It is the first option. DF = DE. It is referring to the lengths of each line, DE and DF look like they are the same. It is not a scalene triangle it is a right triangle. EF is way too long to be equal to DE or DF
Answer:
radius: DF (it is a line segment drawn from the center of the circle to any point on the circle)
diameter: AC ( it is a straight line passing through the center of the circle and intersecting the circle at two distinct points)

Answer:
Step-by-step explanation:
1. (6/a)x + 5 = 4
(6/a)x = -1
6x = -a
x = -a/6
2. 2ax + 7 = 13
2ax = 6
ax = 3
x = 3/a
3. -ax - 20 = -14
-ax = 6
x = -6/a
