Which polynomial correctly combines the like terms and expresses the given polynomial in standard form? 9xy3 – 4y4 – 10x2y2 + x3y + 3x4 + 2x2y2 – 9y4

3x4 – 8x2y2 + x3y + 9xy3 – 13y4
3, x, 4, – 8, x, 2, y, 2, + , x, 3, y, + 9, xy, 3, – 13, y, 4

–13y4 + 3x4 – 8x2y2 + x3y + 9xy3
–13, y, 4, + 3, x, 4, – 8, x, 2, y, 2, + , x, 3, y, + 9, xy, 3

–13y4 + x3y – 8x2y2 + 9xy3 + 3x4
–13, y, 4, + , x, 3, y, – 8, x, 2, y, 2, + 9, xy, 3, + 3, x, 4

3x4 + x3y – 8x2y2 + 9xy3 – 13y4

$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

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake

the answer is b.
