== Posting: I think he died by drowning in the puddle that was in the room with him. He passed out due to starvation which made him fall in the puddle and pass out. == Name: Jeff Schecter  Date: 3/24/10  Type of Posting: 1  Posting: Hello everyone. The man died drowned to death. Another factor in his death was the lack of oxygen in the room. He couldn't breathe due to the lack of air. He may have also starved to death because no one could get food to him. He could have fainted from not have eaten, fallen into the puddle, and then drowned to death in the puddle. That is how the man died.

I think the man suffered from minor suffocation due to the lack of ventilation and airflow in the room. This caused him pass out into the puddle where he inhaled the water into his lungs resulting in him drowning almost immediately.

Evidence also shows, this man could of died of old age. Just like Caroline said, they are a lot of possibilities !

====<span style="color: #ff0044; font-family: 'Lucida Console',Monaco,monospace;"> **Hi everyone. For tonight's homework on Page 499, number 18 was a little complicated. The problem is** <span style="color: #58e854; font-family: 'Lucida Console',Monaco,monospace;">**8k^2-19k+9** <span style="color: #ff0044; font-family: 'Lucida Console',Monaco,monospace;">**. When I multiply term 'a' and term 'c' together I get 72. The problem is that there are no two factors of 72 that add up to 19. I am wondering if this problem is** <span style="color: #8b0fc2; font-family: 'Lucida Console',Monaco,monospace;">**PRIME** <span style="color: #ff0044; font-family: 'Lucida Console',Monaco,monospace;"> **or if i am just missing some factors. Let me know!** ====

**Type of Posting: 3 (in response to Paige)**
===**Hi Paige! For that problem I think that the answer is that it is Prime because the factors of 72 are, 1,72; -1,-72; 2,36; -2,-36; 3,24; -3,-24; 4,18; -4,-18; 6,12; -6,-12; 8,9; and -8,-9. None of those add up to 19 so it must be Prime.**===
