Determine if the expression -8c-9c^4d^2−8c−9c
Leto [7]

Answer:

-8c-9c^4d^2-8c-9c is a polynomial of type binomial and has a degree 6.

Step-by-step explanation:

Given the polynomial expression

-8c-9c^4d^2-8c-9c

Group like terms

=-9c^4d^2-8c-8c-9c

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

=-9c^4d^2-25c

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

-9c^4d^2 has a degree 6.   (adding the exponents of two variables 'c' and 'd').

Thus,

-8c-9c^4d^2-8c-9c is a polynomial of type binomial and has a degree 6.

Masja [62]

Answer:

-24

Step-by-step explanation:

Easy way: 42 - 18 = 24, then translate it to negative 24 because your numbers are negative.

A little bit harder way: -42 + (-18) or -42 + 18 = -24
