(7c + 4) + (2c + 5) Find the Sum.

OpenStudy (anonymous):

7c+4+2c+5 9c+9

OpenStudy (anonymous):

Sweet. That's what I got. Thanks!

OpenStudy (karatechopper):

put like term together 7c+2c+ 4+5 9c+9

OpenStudy (anonymous):

Yeah. I did that but that's not an option!

OpenStudy (anonymous):

So 9c+9, is not the answer?

OpenStudy (anonymous):

No. Apparently not.

OpenStudy (karatechopper):

is 3c+3 one?

OpenStudy (anonymous):

I have the options of 5c - 1, 5c + 9, 9c - 1 and 9c - 9

OpenStudy (karatechopper):

try 9c-9 maybe its a typo

OpenStudy (mathmate):

Or check for typo in the question.

OpenStudy (anonymous):

it won't give me an answer to tell me if its correct or not... so its a chance thing.. yeah its probably a typo

OpenStudy (mathmate):

Should the question not read (7c + 4) - (2c + 5) ?

OpenStudy (anonymous):

It should... But it doesn't

OpenStudy (karatechopper):

hmm chance it

OpenStudy (mathmate):

Then there is a typo in the question.

OpenStudy (anonymous):

Kay. Definitely

OpenStudy (mathmate):

You're sure it's not a minus between the two sets of parentheses?

OpenStudy (anonymous):

No

OpenStudy (mathmate):

Not sure or not a minus?

OpenStudy (anonymous):

The equation stayed the same... Theres no difference in it. Theres no set of parentheses

OpenStudy (mathmate):

Your question has parentheses. Remove the parentheses, and the answers should read 5c+9.

OpenStudy (anonymous):

YOU ARE RIGHT!!!!!! :O Foo. I already put in 9c - 9...

OpenStudy (mathmate):

Anyway, you now know that parentheses are important!

OpenStudy (anonymous):

Yeah! I'm one bit better! Thank you!

OpenStudy (mathmate):

You're welcome!
