Answer:
x2 and 2x
xy2 and 2xy
Step-by-step explanation:

Let's put these as improper fractions.
30 = 60/2. add the 1/2 to get 61/2
13 = 52/4. add the 3/4 to get 55/4

To add/subtract fractions, they must have the same denominator. (bottom no.)
If we multiply the top and bottom of a fraction by something, it stays equal.
We can conclude that 61/2 = 122/4. (bottom multilpies by 2, so does the top)

Now that we have a common denominator, we can subtract.
The "fourths" just sort of acts like a unit. Subtract 55 from 122 to get

.
We can convert this to an improper fraction simply by dividing 67 by 4.
This leaves us with 16, and a remainder of 3. Our answer is

We have that
<span>f(x) = x/4 -3
g(x)= 4x</span>²<span>+2x-4
find (f+g)( x)
step 1
adding the two functions together to create a new function.
[x/4 -3]+[4x²+2x-4]
step 2
making everything have a common denominator of 4 we get:
[(x-12+16x²+8x-16)]/4
step3
combine like terms in numerator
(16x²+9x-28)/4-----------> 4x²+(9/4)x-7
the answer is </span>4x²+(9/4)x-7
