What is the difference? x+5/x+2-x+1/x2+2x
Mrac [35]

Question

x+5/x+2 - x+1/x²+2x

Answer:

= (x² - 4x - 1)/[x (x+2)]

= (x² - 4x - 1)/[x² + 2x]

Step-by-step explanation:

x + 5/x + 2 - x + 1/x² + 2x

We factorise the second denominator to give us :

x + 5/x + 2 - x + 1/x(x + 2)

We find the L.C.M of both denominators which is x(x+2).

[x(x + 5)-(x + 1)] / (x (x + 2))

Expand the bracket

=[x² +5x - x -1] / [x (x + 2)]

=(x² - 4x - 1) / [x (x + 2)]

= (x² - 4x - 1)/ [x (x + 2)]

= (x² - 4x - 1) / [x² + 2x]

Uber charges 1.75 for pickup plus 0.50 per mile. Omar paid 4.25 for a ride. How many miles did he travel?
Sergeu [11.5K]

Answer:

Omar Traveled 5 miles

Step-by-step explanation:

First set up a two step equation, .50x (x is our variable for miles driven) then +1.75= 4.25. Then Subtract 1.75 from itself and from 4.25. You get 2.5, bring everything down. You are now left with .50x=2.5 divide each side by .50 . 2.5 divided by .50 equals 5 and .50 divided by itself is zero, bring down the x and the 2.5. It should now look like this x = 2.5 That is your answer.
