Answer:

= 28/3

Step-by-step explanation:

Let's solve your equation step-by-step.

x(3)−(8)(2)−9x+72=0

Step 1: Simplify both sides of the equation.

x(3)−(8)(2)−9x+72=0

3x+−16+−9x+72=0

(3x+−9x)+(−16+72)=0(Combine Like Terms)

−6x+56=0

Step 2: Subtract 56 from both sides.

−6x+56−56=0−56

−6x=−56

Step 3: Divide both sides by -6.

−6x

−6

−56

−6

Answer:

Investment amount after 9 years = 14715.12$

Explanation:

It is given to use continuous change function, $A(t) = Pe^{rt}$

Here P = Principal = 10500$

r = Rate of increase = 0.0375

t = Number of years = 9

$A(t) = Pe^{rt}\\ \\ A(t) = 10500*e^{0.0375*9}=14715.12$

So, investment amount after 9 years = 14715.12$
