Answer 1

Hi!

Combine like terms.

[1g² + 6g²] [- 6 - 2] + [1h]

I put the like terms in brackets. Solve what's inside each of the brackets.

[7g²] [- 8] + [1h]

You can remove the brackets.

7g² - 8 + h

The answer is B) 7g² - 8 + h

Hope this helps! :)

Answer 2

Note the variables and powers. Combine like terms:

g² - 6 + 6g² - 2 + h

6g² + g² = 7g²

-6 - 2 = -8

7g² + h - 8 is your answer

hope this helps
