Answer:
3
Step-by-step explanation:
List all possible factors of each number. The GCF will be the largest number they both share
Factors of 18: 1, 2, 3, 6, 18
Factors of 15: 1, 3, 5, 15
The largest number they both share is 3, so that is the GCF
The answer is 164 meters
Distance = Sq of 100 + Sq of 130 = 26,900 = Sq root of 26,900 = 164 meters
the fourth answer
7
Because 15 - 6 = 7
