Answer:
7; not a factor
Step-by-step explanation:
2x³ - x² - 4x² + 2x + 6x - 3 + 7
x²(2x-1) - 2x(2x-1) + 3(2x-1) + 7
7 is the remainder.
Hence, not a factor
Answer:
21 roads
Step-by-step explanation:
If each two cities are connected by a direct road, to find the number of roads we just need to solve a combination of 7 choose 2, that is, we need to find all pairs of two cities among the 7 cities:
Combination of 7 choose 2 = 7! / (5! * 2!) = 7*6/2 = 21
So there is a total of 21 roads on the island.
