Answer:

holy this is just substitution child

Step-by-step explanation:

1. y + 2, y = 4

if y is equal to 4, we can replace y in the equation

4 + 2 = 6

2. 6a / 3, a = 3

6 * 3 / 3 = 6

4. x - 7, x = 12

12 - 7 = 5

5. 2c - 4, c = 5

2 * 5 - 4 = 6

7. 2z - 3x

2 (8) - 3(5) =

16 - 15 = 1

8. 6x / (y + z)

(6 * 5) / (2 + 8)

30 / 10 = 3

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.
