(2x-1)(x+4)=0
Step-by-step explanation:
A random zero property of multiplication is taken to find the solution
(2x-1)(x+4)=0
consider a=2x-1 and b=x-4 a.b=0
either a or b or both must be 0
equating both the equations
2x-1=0 or x=4=0 x-4=0
2x-1=0 x=4
2x=1
x=1/2
substitute the values of x in the main equation
[2(1/2)-1][(1/2)+4]=0
Answer: The second term of the expression which is 0.25x is the variable cost which is the extra amount paid for being late.
The expression 2 + 0.25x represents the amount that Ruth paid for the book.
It should be noted that the fixed cost is represented by 2 while the 0.25 represents the variable cost which is the late fee. Also, the x represented the number of days for being late.
In conclusion, the second term of the expression represents the amount that was charged for being late.

Decibel is directly proportional to number of cars passing the point. That is,
69 db ----- 139 cars
x db ----- 17 cars
x = number of cars passing the point per minute on a weekend.
Then,
x= (69*17)/139 = 8.43 db ≈ 8 db
