Ineed these asap 1. write an expression that is not a polynomial. 2. what does gcf stand for? 3. when do you use the difference of squares?

1. 5x+1

2. Greatest Common Factor

3. You use the difference of squares pattern to factor an expression. Use this formula: x^2 - 2^2 = (x+2)(x-2).

$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
