Kipish [7]
The answer is b. Notice that the problem is looking for the reaction to product ratio, which is tricky because it's easy to follow the order of the column and calculate the inverse of it. Check the first ratio, 0.3/2=0.15, we can immediately choose b out of the other 4 choices.

PLS help meee ill give brainiest!!!!
Ede4ka [16]

Answer:

13/4

Step-by-step explanation:

If the f(x) factors into something the same as g(x), then you can cancel:

 

f(x) = 2x2  - 2x + 1 does not factor; therefor

 

( f / g) (x) = (2x2 -2x +1) / ( x + 1 )

 

that is all you can do to it

 

If you were asked to evaluate (f/g)(x) for some x, say x = 3 Then:

 

(f/g)(3) = ( 2(32)  - 2(3) + 1) / (3 + 1)

 

          = (18 - 6 + 1 ) / 4

 

          = 13/4
