Help me with this pls I need help​

Simplifying is about combing like terms.  Just like you cannot combine $4 with 7 inches, you cannot combine 4x with 7y.

The variables (or lack of variables) and their powers identify like terms.

8a)  In 3x - 8 - 4x + 3, the 3x and -4x are like term, while the -8 and the 3 are like terms, so they can be combined.

    3x - 8 - 4x + 3 = -x - 5

8b) y - 9 - 7 - 6y = -5y - 16

because y - 6y = -5y and -9 - 7 = -16

8c) Here only terms with the same powers combine.

In , the 's are the like terms, while the ones with out the exponents are like terms:

8d) Similar to 8c, can you try this one on your own?

8e) It doesn't matter how many terms there are, you still just combine like terms.

    3k - 5 + 8 - k + 1 - 4k = -2k + 4

8f) Can you try this one on your own?  Remember numbers without variables are not like terms with 's and those are not like terms with 's.

9a) The concept is still the same, but remember that like terms must have the same variables and those variables must have the same exponents.   is not a like term with or .

9b)

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
