Determine if the expression -8c-9c^4d^2−8c−9c 4
d
2
is a polynomial or not. If it is a polynomial, state the type and degree of the polynomial.

anyone know?

is a polynomial of type binomial and has a degree 6.

Step-by-step explanation:

Given the polynomial expression

Group like terms

Add similar elements: -8c-8c-9c=-25c

Thus, the polynomial is in two variables and contains two, unlike terms. Therefore, it is a 'binomial' with two, unlike terms.

Each term has a degree equal to the sum of the exponents on the variables.

The degree of the polynomial is the greatest of those.

25c has a degree 1

has a degree 6.   (adding the exponents of two variables 'c' and 'd').

Thus,

is a polynomial of type binomial and has a degree 6.

$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
