You would want to avoid rocky ground and mountains unless you wanted to protect yourself, so avoiding new england and also high places like colorado.
Explanation:
This is a product of two expressions that is equal to zero. Note that any xxx value that makes either (x-1)(x−1)left parenthesis, x, minus, 1, right parenthesis or (x+3)(x+3)left parenthesis, x, plus, 3, right parenthesis zero, will make their product zero.

(x−1)
↙
x−1=0
x=1
(x+3)=0
↘
x+3=0
x=−3
Substituting either x=1x=1x, equals, 1 or x=-3x=−3x, equals, minus, 3 into the equation will result in the true statement 0=0, equals, 0, so they are both solutions to the equation.
No.
The speed of sound in water depends on the temperature and pressure. As you go deeper, the pressure increases and the speed of sound increases.
The most important thing that the designers should take into account are the potential earthquakes - the buildings should be able to withstand the shaking of the ground.
