Adam writes 18y to simplify an expression with three like terms. what could the expression be?

Step-by-step explanation:

5y + 6y + 7y = 18yany numbers that add(or subtract) to equal 18, stick them before the y

or it could be : 10y + 10y - 2y = 18y or 5y + 10y + 3y or 30y - 20y + 8yI could go on forever...lol

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

answer: graph 2
