Question

Help I need this now.

Answer 1

Rosa is incorrect because if we substitute b, for the number 4. The answer is not equal to 10.

Explanation:

(3+9b)-2b=10

(3+9*4)-2*4=10

(3+36)-8=10

39-8=10

31=10

It is incorrect because the numbers are not the same.

Answer 2

I think Rose isn't correct.
