First you need to get a common denominator. The first two problems already have a common denominator, so you just have to find the sum and difference of the two problems, respectively.
6.) (9y-3)/(y^2-5)
8.) 3/xy^3
Two find a common denominator, find the smallest value that has BOTH denominators as factors.
10.) 8x^3*y^3 is the common denominator
Answer: 2/(8*x^3*y^3)
12.) Factor x^2 + 4x + 4 to get (x+2)(x+2)
Therefore, x+2 is already part of x^2 + 4x + 4
(x+4)/(x^2+4x+4)
14.) Factor both denominators..
4(y+2) and y(y+2)
So the common denominator would be 4y(y+2)
The first fraction is missing a "y" so multiply the numerator by y to get y^2
The second fraction is missing a "4" so multiply the numerator by 4 to get 4
(y^2 - 4)/(4y(y+2))
So can factor the numerator to get (y+2)(y-2). There if a (y+2) on top and bottom so they cancel out.
Answer: (y-2)/4y
The correct answer to the question you asked is B.
Hi,
side=3600 foot
area=side*side
area=3600*3600
area=129600<span>0</span>0 square foot
cost=area*rate
cost=12960000*0.75
cost=Rs.(or whichever currency)9720000
Hope this helps you.
All you need to do is add the miles from Eaton to Baxter and from Baxter to Wellington to get your answer...
42 + 37 = 79 Now we need to add the fractions

To add we need a
common denominator. 2 and 5 can both go into 10, so that will be a our common denominator.
Now you have...
which is equal to 
add that to the 79 we got earlier ...
The toal and final answer is
miles !Hope I helped and remember to vote this as the brainliest answer ! :)
