10008 hours per 3 years is average of 3336 hours per year, or about 9.1 per day.
v(x) has the largest value when x=4.
x = 2
step 1 :
(2 • (5x + 2) • 2) - 48 = 0
step 2 :
4 • (5x + 2) - 48 = 0
Pulling out like terms :
20x - 40 = 20 • (x - 2)
step 4 :
20 • (x - 2) = 0
Equations which are never true :
Solve : 20 = 0
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
Solve : x-2 = 0
Add 2 to both sides of the equation :
x = 2
