So it is asking you to group like term so
x terms can be grouped/added/subtracted to other x terms, but not to x^2 or x^3 terms
x^2 terms to x^2 and so on so
1. 9-3k+5k=
9+(5k-3k)=
9+2k
2. k^2+2k+4k=
k^2+(2k+4k)=
k^2+6k=
Answer:
There is no problem
Step-by-step explanation:
If she is bringing 2/3 to school, then she is not bring 1/3
1/3 (45) = 45/3 = 15.....so she is not bringing 15 cookies
or u can do it this way...
she is bringing 2/3...
2/3(45) = 90/3 = 30 ....she is bringing 30
45 - 30 = 15....not bringing 15.
Always one. 0/0 is indeterminate
