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.

Since Matrix A is added with Matrix B
then each component must be added to its corresponding component
a11+b11=0
a11=-b11
if
a11*b11=-16
then a11=+4 and b11=-4 or a11=-4 and b11=4
a11 is postive so our answer should be
a11=4 and b11=-4
