12. Haley and Lindsy disagree about the answer to another problem that Mrs. Johnson assigned. Haley says that (c^2+c)/(c^2) can’t be simplified. Lindsy says that it simplifies to c.

What do you think?

A Haley is right because nothing cancels.
B Lindsy is right because c^2 cancels.
C They’re both right. Either answer is acceptable.
D They’re both wrong. The correct answer is (c+1)/(c)
E They’re both wrong. The correct answer is (2c)/(c^2)

D.

By Lindsay's logic, if you substitute number for the values..then say random c is 3 and c ^2 is 9 then you have (9 plus 3)/3 is c (3) and 12/3 is 4.

But as in D, (c+1)/c (factoring out a "c" on both and bottom and canceling it out leads to (9+3)/9 is (3+1)/3 or 4/3 or 11/3

Its D.
It becomes c(c+1)/c^2 when c is taken out from numerator. Then that c cancels out with one c in the denominator and the answer is obtained.

Man, it's been a while. I almost forgot how much I hate math. I think it's A. the parenthesis means that you have to figure out what's inside each one before you can divide and so you can't simplify without knowing "C".

D. the correct answer is (c+1)/c

when you cancel out the numerator you have to take in part the whole numerator not just a part of it.

D

(C^2+C) simplifies to (C)(C+1).

(C^2) can simplify to (C)(C).

Therefore, you can cross out a c from both the numerator and the denominator and (C+1)/(C) is your answer.

B. Lindsy is right the c squared's cancle

D is correct. multiply numerator and denominator by (1/c)/(1/c).

the answer is b lindsay is right because c^2 cancels...

if u put it in this form: cc+c/cc the cc cancels coz its cc dvded by itself whch is one..so the remaining is 1c or c..
