In rolling one die, there are 6 possible outcomes because each die has 4 faces. The number of outcomes when rolling n dice is equal to 6^n. By this, the number of outcomes when 2 dice are rolled is 36, 216 for 3 dice, and so on.
We have been given that the upstream speed is
and the down stream speed is
.
Let the fisherman traveled a distance of x miles.
The total time of the trip is 6 hours.
Relations between speed (s), time (t) and distance (d) is 
Hence, 
Time upstream + time downstream = 6

lcm = 10

=> 
Cross multiplying, 
x = 20 miles .. Answer.

The value of x = (- 1 + 2√2)/4 satisfies the given equation.
<h3>What is an Equation ?</h3>
An equation is a mathematical statement formed when two algebraic expressions are equated by an equal sign.
The equation given is
(4x + 1)² - 8 = 0
x = (- 1 + 2√2)/4
To check whether it satisfies the equation
( 4 * ( (- 1 + 2√2)/4) +1)² -8 = 0
(-1 + 2√2 +1)² - 8 = 0
(2√2)² -8 = 0
8-8 = 0
As LHS = RHS ,
hence the value of x = (- 1 + 2√2)/4 satisfies the given equation.
