What is the difference x +5/ x +2 - x + 1/x ^2 + 2x?
Lisa [10]
ANSWER
The difference is,

\frac{ {x}^{2} + 4x - 1}{ {x}^{2} + 2x}

EXPLANATION

To find the difference, we just have to simplify the expression.

The given expression is

\frac{x + 5}{x + 2} - \frac{(x + 1)}{ {x}^{2} + 2x}

We factor the denominator of the second fraction to get,

=\frac{x + 5}{x + 2} - \frac{(x + 1)}{ x( x+ 2)}

We can now see clearly that the LCM is

x(x + 2)

We collect LCM to get,

=\frac{x(x + 5) - (x + 1)}{ x( x+ 2)}
We now expand the bracket to obtain,

=\frac{ {x}^{2} + 5x - x - 1}{ {x}^{2} + 2x}

This gives us,

=\frac{ {x}^{2} + 4x - 1}{ {x}^{2} + 2x}

The cost of a car rental is ​$42 per day plus 20 cents per mile. you are on a daily budget of ​$98. write and solve an inequalit
gayaneshka [121]
R= $42 rental cost per day
Mileage= $0.20 per mile
m= number of miles driven
Budget= $98 per day

EQUATION
$98> $0.20m + $42

SOLUTION
$98> $0.20m + $42
subtract 42 from both sides
$56> $0.20m
divide both sides by $0.20
280> m

They have to drive less than 280 miles per day to stay within their $98 budget.

SAME SOLUTION INEQUALITIES
Set up the equations with new numbers, substitute 280 for m and pick another variable to solve for. I chose to solve for total rental cost.

m= 280 miles per day
R= Rental cost per day

R> $0.10(280) + $50
R> $28 + $50
R> $78

Equation #1
$78> $0.10m + $50

----------
m= 280 miles per day
R= Rental cost per day

R> $0.18(280) + $44
R> $50.40 + $44
R> $94.40

Equation #2
$94.40> $0.18m + $44

ANSWER: 280> m; They have to drive less than 280 miles per day to stay within their $98 budget.

Equation #1: $78> $0.10m + $50
Equation #2: $94.40> $0.18m + $44

Hope this helps! :)
