Identify the quadratic function(s). (select all that apply.)
8-5x = 4(3x - 1)
(48 + 272a-1)+1=0.
1 2y + 2/3y - 5) = 0
2bb-7)+b=0

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.

[15 points]find the quotient with the restrictions. (x^2 - 2x - 3) (x^2 + 4x + 3) ÷ (x^2 + 2x - 8) (x^2 + 6x + 8)

This is about circle theorems. someone asap : (
