Answer:

Ali's solution is incorrect. Ali had to add both the terms and should get 10y answer, and not multiply both terms and get answer 9y^2 which is wrong. Step-by-step explanation: Ali simplifies the expression 9y+y to 9y2.

Step-by-step explanation:

Answer:

Ali is incorrect because 9y2 would be 9*y*2 = 18y.

We all know that 9y+y is not going to be 18y

So 9y+y since 9+1 = 10. it simplifies to 10y

10y ≠ 18y

Ali is incorrect
