Answer:
answer B is correct
Step-by-step explanation:
Hello,
this is not allowed to divide by 0 so we need to find the zeros of
![x^2+2x-15=0](https://tex.z-dn.net/?f=x%5E2%2B2x-15%3D0)
![x^2-3x+5x-15=0\\ x(x-3)+5(x-3)=0\\ (x+5)(x-3)=0\\ x=-5 \ \ or \ \ x=3](https://tex.z-dn.net/?f=%3C%3D%3E%20x%5E2-3x%2B5x-15%3D0%5C%5C%3C%3D%3E%20x%28x-3%29%2B5%28x-3%29%3D0%5C%5C%3C%3D%3E%20%28x%2B5%29%28x-3%29%3D0%5C%5C%3C%3D%3D%3E%20x%3D-5%20%5C%20%5C%20%20or%20%20%5C%20%5C%20x%3D3)
we need x different from -5 and from 3
answer B is correct
hope this helps
Answer:
(g - 14)
Step-by-step explanation:
![{g}^{2} - 28g + 196 \\ = {g}^{2} - 14g - 14g+ 196 \\ = g(g - 14) - 14(g - 14) \\ = (g - 14)(g - 14) \\](https://tex.z-dn.net/?f=%20%7Bg%7D%5E%7B2%7D%20%20-%2028g%20%2B%20196%20%5C%5C%20%20%3D%20%20%7Bg%7D%5E%7B2%7D%20%20-%2014g%20%20-%2014g%2B%20196%20%5C%5C%20%20%3D%20g%28g%20-%2014%29%20-%2014%28g%20-%2014%29%20%5C%5C%20%20%3D%20%28g%20-%2014%29%28g%20-%2014%29%20%5C%5C%20)
A ratio is used to describe how two or more quantities are related. For example, we might say that a fruit drink calls for sugar crystals to be mixed with water in a ratio of 2:8. This means that for every 2 scoops sugar crystals, there will need to be 8 ounces of water. If there were 200 scoops of sugar crystals, there would need to be 800 ounces of water.
