Given rate is = 7% or 0.07
Total amount needed = $12000
Time = 4 years
Here, the deposit is compounded semiannually, means twice per year and this gives 8 annual compounding periods in 4 years.
The equation becomes:
P= 
P = 
Solving it, we get P = $ 9112.93
Hence $9112.93 should be deposited today.

Algebra
The inverse of -9n is dividing by -9.

Answer:
x² = (x-2) (x+3)
and
x = 6
Step-by-step explanation:
x² = (x-2) (x +3)
x² = x² + 3x - 2x - 6
x² = x² + x - 6
moving x² and -6 from LHS to RHS
x² - x² + 6= x
6 = x
x = 6
