Because the ones place is under 5, we round down, and 392 becomes 390 when rounded to the nearest 10
Answer:
![\frac{2(x^{2} + 5x + 3)}{(x+3)(x+5)}](https://tex.z-dn.net/?f=%5Cfrac%7B2%28x%5E%7B2%7D%20%2B%205x%20%2B%203%29%7D%7B%28x%2B3%29%28x%2B5%29%7D)
Step-by-step explanation:
We need to sum the following two expressions:
![\frac{x}{x+3} + \frac{x+2}{x+5}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Bx%2B3%7D%20%2B%20%5Cfrac%7Bx%2B2%7D%7Bx%2B5%7D)
![\frac{x(x+5) + (x+2)(x+3)}{(x+3)(x+5)}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%28x%2B5%29%20%2B%20%28x%2B2%29%28x%2B3%29%7D%7B%28x%2B3%29%28x%2B5%29%7D)
expanding the polynomial in the numerator:
![\frac{2x^{2} + 10x + 6}{(x+3)(x+5)}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%5E%7B2%7D%20%2B%2010x%20%2B%206%7D%7B%28x%2B3%29%28x%2B5%29%7D)
![\frac{2(x^{2} + 5x + 3)}{(x+3)(x+5)}](https://tex.z-dn.net/?f=%5Cfrac%7B2%28x%5E%7B2%7D%20%2B%205x%20%2B%203%29%7D%7B%28x%2B3%29%28x%2B5%29%7D)
This is the most simplified form we can get:
![\frac{2(x^{2} + 5x + 3)}{(x+3)(x+5)}](https://tex.z-dn.net/?f=%5Cfrac%7B2%28x%5E%7B2%7D%20%2B%205x%20%2B%203%29%7D%7B%28x%2B3%29%28x%2B5%29%7D)
