Answer:
her speed in still water = 11 km/hour
the speed of the current = 9 km/hour
Step-by-step explanation:
x = Ritu's speed of rowing.
y = the sites of the river water flowing
x + y = 20 km / 2 hours = 10 km / hour
x - y = 4 km / 2 hours = 2 km / hour
x = 2 + y
2 + y + y = 20
2y = 18
y = 9 km/hour
x = 2 + y = 2 + 9 = 11 km/hour

Answer:
C
Step-by-step explanation:
Consider the trinomial
We can rewrite it as
Now group first two terms and last two terms:
The common factor in first two terms is and the common factor in last two terms is Use the distributive property for both groups of terms:
so
Now you can see that is a common factor, thus
Since the trinomial can be represented as a product of binomials, this trinomial is not prime.
