To solve this problem you must apply the proccedure shown below:
1. You have the following expression given in the problem above:
<span>7/x^2-3x - 1/x^2-9
</span>
2. When you factor the denominator, you obtain:
<span>7/x(x-3) - 1/(x+3)(x-3)
3. By simplifying the expression, you obtain:
3(2x+7)/x(x+3)(x-3)
</span> 3(2x+7)/x(x^2-9)
The answer is: 3(2x+7)/x(x^2-9)

Answer:
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount deposited.
P represents the principal or amount deposited.
R represents interest rate
T represents the duration in years.
From the information given,
P = 2500
R = 1.5%
T = 30 years
I = (2500 × 1.5 × 30)/100 = $1125
the account balance be after 30 years is
1125 + 2500 = $3625
