A. Using \( k \) as the constant of variation, write the equation of variation for each of the followin 1. \( W \) varies jointly as \( c \) and the square of \( a \) and inversely as \( b \). 2. \( P \) varies directly as the square of \( x \) and inversely as \( s \). 3. The electrical resistance \( R \) of a wire varies directly as its length \( l \) and inversely as \( t \) square of its diameter \( d \). 4. The acceleration \( A \) of a moving object varies directly as the distance \( d \) it travels a inversely as the square of the time \( t \) it travels. 5. The pressure \( P \) of a gas varies directly as its temperature \( t \) and inversely as volume \( V \).

Divide, and then simplify, if possible. \[ \frac{n^{2}+6 n-27}{n} \div \frac{3-n}{n} \]
