Which ones are like terms and how can you tell? -8h 4h 3t 7t -4e 3e -2b b

1) -8h and 4h

2) 3t and 7t

3) -4e and 3e

4) -2b and b

Step-by-step explanation:

They all have the same variable as the other in the pair. There aren't any other variables added or exponents.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
