Answer:
Step-by-step explanation:
A truck is rented at $40 per day plus a charge per mile of use. The truck traveled 15 miles in one day, and the total charge was $115.
Let x be the charge per mile of use (dollar per mile)
The truck traveled 15 miles in one day. the charge for 15 miles is 15x
A truck is rented at $40 per day
So charge is
total charge was 115
So the equation becomes

Answer:
Step-by-step explanation:
We need to factor out numerator and denominator in order to simplify the rational expression by cancelling common factors.
Numerator : x^3 - 4 x = x (x^2 - 4) = x (x - 2) (x + 2)
Denominator (factoring by grouping):
x^2 - 5 x + 6 = x^2 - 3 x - 2 x + 6 = x (x - 3) - 2 (x - 3) = (x - 3) (x - 2)
Then we can cancel out the common factor (x - 2) in both numerator and denominator, leading to:
x (x + 2) / (x - 3) = (x^2 + 2)/ (x-3)
Answer:
C.
Step-by-step explanation:
Given problem is .
Now we need to evaluate the given limit.
If we plug , into given problem then we will get 0/0 form which is an indeterminate form so we can apply L Hospitals rule
take derivative of numerator and denominator
=2
Hence choice C is correct.
