(5x² - 3x + 5) - (3x² - 4x - 7) Distribute/multiply - into (3x² - 4x - 7)
5x² - 3x + 5 - 3x² + 4x + 7 Combine like terms
2x² + x + 12
The answer is A
$75.14. formula as follows ($79.99 - (($79.99/100)x12)) + ((($79.99/100)x12)/100)*6.75)
The experimental probability is 9/20 or 45%. Hope this helps!
