Answer:
In 4 years, you will have $2,635.38
Step-by-step explanation:
The formula for annual compound interest, including principal sum, is:
A = P (1 + r/n) ^ (nt)
Where:
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for
Note that this formula gives you the future value of an investment or loan, which is compound interest plus the principal. Should you wish to calculate the compound interest only, you need this:
Total compounded interest = P (1 + r/n) ^ (nt) - P

Answer:
The answer to your question is:       (2a + 2b)²
Step-by-step explanation:
a² + b² = z
ab = y
Which is equivalent to 4z + 8y ?
Substitution 
                                      4(a² + b²) + 8(ab) 
Simplify                        4a² + 4b² + 8ab
Order                            4a² + 8ab + 4b²       It's a perfect square trynomial
Factorize                     (2a + 2b)²
 
        
                    
             
        
        
        
26 27 28 29 30 so 25 24 23 22 21---so 30 is the awnser
