What value is added to both sides of the equation x2 − 8x = −10 in order to solve by completing the square? −8 16 −4 4

16

Step-by-step explanation:

to complete the square we add (b/2) ^2 to each side where b is the coefficient of the x term

(-8/2) ^2 = (-4)^2 = 16

add 16 to each side

$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
