Answer: False
Step-by-step explanation:
It is false because I believe 8x 2 was meant to be put as 8x^2, but either way a like term means they are all alike. 7x and -9x are both like terms because they have the term "x." 7yx and -9yx would also be like terms because they both have "yx." However, 7yx and -9x would not be like terms because their terms are not similar.
Hope this helps and good luck!
