is this anwer correct
9a^2b + 3c + 2a^2b + 5c =
ANSWER : 11a^2 + 8c^2
your answer is not correct
9a^2b + 3c + 2a^2b + 5c
= 11a^2b + 8c
11a^2 + 8c
Where did you get c^2?
9a^2b + 2a^2b= 11a^2
3c+5c = 8c^2
so the answer IS 11a^2 +8c^2
No, it isn't.
Both your last equations, and "the answer" are wrong. Read again the posts of Reiny and PsyDAG.
there are choices
a) 19a^2bc
b) 11a^2b+8c
c) 11a^4b^2 +8c^2
d) 19a^2b^2c^2
No, the given answer is not correct.
To simplify the expression 9a^2b + 3c + 2a^2b + 5c, you need to combine like terms.
First, let's group the terms with similar variables together:
(9a^2b + 2a^2b) + (3c + 5c)
Now, combine the coefficients of the like terms:
11a^2b + 8c
Therefore, the correct simplification of the expression is 11a^2b + 8c.
