But "there" can also be referred to Meadowland, and not "meadows". In "in Meadowland, a major sport center is located there" Ahh well, I give up and take B as the answer.. Thank you all.

**English-reading**

No. cant be. It's multiple choice. Choice A + D doesn't contribute to the passage. Choice A is wrong because one can assume the land is small, if compared with others . Choice D is false because it didnt say the previous price. am I on the ball-part?

**English-reading**

But it says the sports complex is located in Meadowland, supposely a city. Whereas the meadows (foul smell) mostly like to contribute a swampland. Or Im just too confused?

**finding directrix. Am I right?**

oh! Ok thank you. I already do have it graphed as that is required. Thank you for all the help.

**finding directrix. Am I right?**

the equation of the parabola is (y-5)^2=5(x+8). Now I asked this earlier but that thread is farther down so no one sees it. He said the directrix is -9.25 but I think it is -1.25. Am I right?

**chemistry-stoichiometry**

All you need to do is convert to moles AuCL3 and then use the mole ratio and convert back to grams Cl2 64.0*(1 mol/233g)*(3 mol Cl2/2mol AuCl3)*70.906gCl2= 29.214

**Algebra 2**

Sorry but I am trying to understand your reasoning for the directrix. How did you get -9.25. I would think it would be -1.25.

**Algebra 2**

When you say vertex, you mean the center so what about vertices and co-vertices. And there is only 1 foci?

**Algebra 2**

Another thing, would a=1.25? Because 4*1.25 equals 5

**Algebra 2**

Actually, I belive you made a mistake there. Multiplying both sides by five would get my -10y and therefor, I would add 25 to both sides right?

**Algebra 2**

Wow thanks for that. Could you help me with all the other things I listed above. This stuff is confusing to me.
