Answer:

Step-by-step explanation:

1)  x - 21x  = 5

x   = x * 1

21x = x * 21

GCF = x

x - 21x = 5

x*(1 -21) = 5

x * (-20) = 5

-20x = 5

x =5/-20

x = -1/4

2) 6n² = 6 * n * n

30n   = 6 * 5 * n

GCF = 6*n = 6n

6n² + 30n = 0

6n*(n + 5 ) = 0

6n = 0      or n + 5 = 0

n = 0             n = -5

n = 0 or -5

3400 dollars is placed in an account with an annual interest rate of 8. 25%. How much will be in the account after 25 years, to
OLEGan [10]

The final amount in the account after 25 years is $24670.42.

<h3>How do you calculate the final Amount after 25 Years?</h3>

Given that 3400 dollars are placed in an account with an annual interest rate of 8.25% for 25 years.

The final amount in the account is calculated by the formula given below.

A = P ( 1 + \dfrac {R}{100})^T

Where A is the final amount, P is the initial principal balance, R is the interest rate, T is the time period.

The final amount is given below.

A = 3400 ( 1 + \dfrac {8.25}{100})^{25}

A = 3400 (7.256005874)

A = 24670.41997= 24570.42

Hence we can conclude that the final amount in the account after 25 years is $24670.42.
