Area = 2m^8 - 6m^4 + 4.5

Step-by-step explanation:

Given

Base = 2m^4 - 3

Height = 2m^4 - 3

a boat going upstream at 4 mph then travels downstream at 10 mph. what is the rate of the boat in still water​
elixir [45]

Answer:

7 mph

Step-by-step explanation:

If b is the rate of the boat, and s is the rate of the stream, then:

b − s = 4

b + s = 10

Solve the system of equations with substitution or elimination.  Using elimination, add the equations together:

2b = 14

b = 7

The boat's rate is 7 mph.
