There are no like terms

Nnesha (nnesha):
if the variables are the same and the same exponent then those 2 terms are like terms
you can combine their coefficient

Lol @Nnesha

Second one, should (if I'm correct) be 2+17x-5x+9
---->11+ 12x
OpenStudy (anonymous):
because you add 9 plus 2, and then subtract 5x from 17x
Nnesha (nnesha):
example 3x+4x are like terms
you can combine their coefficient
(3+4)x=7x

I think the second one is A
OpenStudy (anonymous):
Also, if I am correct, 3(5y+6)-4, should be 15y+14
Nnesha (nnesha):
explain please.let him/her find the answer.
OpenStudy (anonymous):
Of course. Here is why I believe so. You need to distribute.
OpenStudy (anonymous):

Hopefully you understand, if not I can explain :)
OpenStudy (anonymous):
Okay. There are all correct?
OpenStudy (anonymous):
OpenStudy (anonymous):
The ones I answered should be correct
OpenStudy (anonymous):
Number one is incorrect

OpenStudy (anonymous):
Number 1 is incorrect because those are not like terms, it should be A
OpenStudy (anonymous):
Reasoning being that y and 1.2y are like terms, hence the y :)
OpenStudy (anonymous):
Okay thx soo much
OpenStudy (anonymous):
You're welcomed :)
OpenStudy (anonymous):
