Answer:
- JK = 6.5
- KM = 5.5
- not congruent
Step-by-step explanation:
JK = K-J = (-4) -(-10.5) = 6.5
KM = M -K = 1.5 -(-4) = 5.5
6.5 ≠ 5.5, so the segments are not congruent.

Answer:
16200
Step-by-step explanation:
30000 * (1-0.05)¹² = 30000 * 0.54 = 16200
1st year : 30000 * (1-0.05) = 28500
2nd year: 28500 * (1-0.05) = 30000 * (1-0.05)² = 27075
....
12th year: 30000 * (1-0.05)¹² = 16200
