is this anwer correct
9a^2b + 3c + 2a^2b + 5c =

ANSWER : 11a^2 + 8c^2

  • math -

    your answer is not correct

    9a^2b + 3c + 2a^2b + 5c
    = 11a^2b + 8c

  • math -

    11a^2 + 8c

    Where did you get c^2?

  • math -

    9a^2b + 2a^2b= 11a^2
    3c+5c = 8c^2

    so the answer IS 11a^2 +8c^2

  • math -

    No, it isn't.

    Both your last equations, and "the answer" are wrong. Read again the posts of Reiny and PsyDAG.

  • math -

    there are choices
    a) 19a^2bc
    b) 11a^2b+8c
    c) 11a^4b^2 +8c^2
    d) 19a^2b^2c^2
