Answer:

\dfrac{1}{2x(x-1)}

Step-by-step explanation:

Given

\dfrac{x^2+2x+1}{x^2-1}\div (2x^2+2x)

Consider the numerator:

x^2+2x+1=(x+1)^2

Consider the denominator:

x^2-1=(x-1)(x+1)

Hence, the fraction becomes

\dfrac{(x+1)^2}{(x-1)(x+1)}=\dfrac{x+1}{x-1}

Consider the expression in brackets:

2x^2+2x=2x(x+1)

Divide:

\dfrac{x^2+2x+1}{x^2-1}\div (2x^2+2x)=\dfrac{x+1}{x-1}\div 2x(x+1)=\dfrac{x+1}{x-1}\times \dfrac{1}{2x(x+1)}=\dfrac{1}{2x(x-1)}

A car rental agency charges ​$33 per day to rent a car and ​$11.95 per day for a global positioning system​ (GPS). Customers are
harkovskaia [24]

(a) b = (33+11.95)d + 55.5

(b) The bill for a 5 day rental is $280.25

Step-by-step explanation:

Given,

Rent of car per day = $33

Rent of GPS per day = $11.95

Cost of gas = $3.70 per gallon

Cost of 15 gallons = 3.70*15 = $55.5 per tank

a) Write a function rule for the total bill b as a function of the days d the car is rented.

Let,

d be the number of days.

Total bill = (Rent of car per day + Rent of GPS per day )* Number of days + Cost of tank

b = (33+11.95)d + 55.5

b) What is the bill for a 5 day​ rental?

Putting d=5 in above function

b = (33+11.95)*5+55.5\\b=(44.95)*5+55.5\\b=224.75+55.5\\b=280.25

The bill for a 5 day rental is $280.25
