What is the difference of the two polynomials?

(7y^2 + 6xy) – (–2xy + 3)

a.) 7y^2 + 4xy – 3

b.) 7y^2 + 8xy – 3

c.) 7y^2 + 4xy + 3

d.) 7y^2 + 8xy + 3

B) 7y² + 8xy - 3 .

Step-by-step explanation:

Given  : (7y² + 6xy) – (–2xy + 3).

To find : What is the difference of the two polynomials.

Solution : We have given

(7y² + 6xy) – (–2xy + 3).

Removing the pantheists

(7y² + 6xy) + 2xy - 3).

Combine like terms

7y² + 8xy - 3 .

Therefore, B) 7y² + 8xy - 3 .

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
