Step-by-step explanation:
that just is the answer use pyth theorem them add 8
it is 3 cuz if u multiply
Combine the like terms -
2x+6x=8x
8+5=13
8x+13 Is the simplified version
Answer:
The speed of the boat in still water u = 8
Step-by-step explanation:
Let speed of the boat = u
Speed of the current = v = 4
Given that the first boat to travel 3 miles upstream and back in a total 1 hour.
So
Since v = 4
By solving above equation
u = 8 , - 2
Since u = -2 is not valid.
⇒ u = 8
This is the speed of the boat in still water.
it's 88.1 x 10 to the power negative 2
and
0,0881
Step-by-step explanation:
88.1÷1000=0,0881
