At president Bush's inauguration in 2005,the newspaper headlines stated there were about 400,000 people in attendance.
As the newspaper rounded to the nearest ten thousand , so the largest number of people will be = 404000 (if it were 405000, it will round to 410000 which is wrong)
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.
