Answer:
33%
Step-by-step explanation:
9 - 6 = 3
3 / 9 = 0.33
0.33 x 100 = 33%
Amount of what you have divided by the total amount of something, times by 100 gives you the percentage
The given expression is :
2xx+3-5(x-2)
We know that, 

Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
