= 5 packs
Answer:
factors
Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
First, notice that we can cancel out an x in the second term. Thus:
![\frac{3x^2}{x^2+x} =\frac{3x^2}{x(x+1)} =\frac{3x}{x+1}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%5E2%7D%7Bx%5E2%2Bx%7D%20%3D%5Cfrac%7B3x%5E2%7D%7Bx%28x%2B1%29%7D%20%3D%5Cfrac%7B3x%7D%7Bx%2B1%7D)
As with the last question, change the sign to multiplication and "flip" the second term:
![\frac{2x-1}{x+1}\cdot \frac{x+1}{3x}](https://tex.z-dn.net/?f=%5Cfrac%7B2x-1%7D%7Bx%2B1%7D%5Ccdot%20%5Cfrac%7Bx%2B1%7D%7B3x%7D)
Multiply straight across:
![=\frac{(2x-1)(x+1)}{(x+1)(3x)}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%282x-1%29%28x%2B1%29%7D%7B%28x%2B1%29%283x%29%7D)
Cancel the (x+1) term:
![=\frac{2x-1}{3x}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2x-1%7D%7B3x%7D)
Cannot be simplified further.
