This isn't an important question, so if you have other questions to answer move on.
my friend says he can make 2 equal 1
i say he cant
he posts this

a = b
a^2 = ab
a^2 - b^2 = ab - b^2
(a+b) (a-b) = b(a-b)
a+b=b
b+b = b
2b = b

his opinion: yes this works
my opinion: you can't tack on a bunch of stupid stuff and say it works
math geniuses tell me the technicalities and if it works please
i know this is just some dumb trick but i need to feel good about myself

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

$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
