OpenStudy (truwhovian11):

@sooobored @jabez177 @Hayhayz @Love.Bug

OpenStudy (sooobored):

any attempt yet?

OpenStudy (truwhovian11):

yeah my attempts were wrong

OpenStudy (sooobored):

please show me so i have an idea where you went wrong

OpenStudy (sooobored):

love's third answer was incorrect if you saw it

OpenStudy (love.bug):

1.) 1k? 2.) 12r-4? 3.) 10n-7?

OpenStudy (truwhovian11):

for #1 i got 1k #2 i got 4-4r #3 i got 10n-13

OpenStudy (sooobored):

1 is right, as a note, "1k" is the same as "k" since anything times 1 is the same value

OpenStudy (truwhovian11):

okay what about the others

OpenStudy (sooobored):

3 is fine, but 2 is wrong

OpenStudy (truwhovian11):

okay so what did i do on two that was wrong

OpenStudy (sooobored):

12r-8-12 unless the question is different than as shown, your answer 2 was absolutely completely wrong

OpenStudy (sooobored):

you just add up like terms or we can group them up 12n +(-8-12)

OpenStudy (sooobored):

we'll notice that there is no other term with the variable n so we can leave 12n alone the only like terms we see are -8 and -12 adding those together and you get?

OpenStudy (truwhovian11):

-20?

OpenStudy (sooobored):

yea so add that together with 12n the complete answer is?

OpenStudy (truwhovian11):

12n+20

OpenStudy (truwhovian11):

?

OpenStudy (sooobored):

you wrote -20, whered +20 come from?

OpenStudy (truwhovian11):

oops i meant 12n-20

OpenStudy (sooobored):

yup

OpenStudy (sooobored):

well except, variable is r not n soooo

OpenStudy (sooobored):

just make sure the proper variable is in the answer

OpenStudy (truwhovian11):

oops i meant to put n oops

OpenStudy (sooobored):
