Find the zeros of the function. Write the smaller solution first, and the larger solution second.
f(x) = (x + 4)^2 - 25

x = -9,1

Step-by-step explanation:

f(x) = (x + 4)^2 - 25

Set the function equal to zero

0 = (x + 4)^2 - 25

Add 25 to each side

25 = (x + 4)^2 - 25+25

25 = (x + 4)^2

Take the square root of each side

±sqrt(25) = sqrt( (x + 4)^2 )

±5 = x+4

Separate into two equations

5 = x+4    - 5 = x+4

Subtract 4 from each side

5-4 = x+4-4    -5-4 = x+4-4

1 = x                 -9 =x

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
