(2.) A rectangular vegetable garden will have a width that is \( 2 \) feet less than the length, and an area of \( 48 \) square feet. If \( x \) represents the length, then the length can be found by solving the equation:
\( x ( x - 2 ) = 48 \)
What is the length, \( x \) , of the garden? The length is feet. The solution is
x=8
Joe earns \( \$ 9 \) per hour. He worked \( x \) hours on both Wednesday and Friday, and \( 8 \) hours on both Tuesday and Saturday. Write an expression to represent how much Joe earned.
If a virus spreads at a rate that can be modeled by the exponential function \( A ( t ) = ae ^ { r t } \) , how many people will be infected after \( 5 \) days if initially \( 3 \) people are infected and the growth rate is \( 40 \% \) ?
