Please help im so lost lol

B, C, and E

Step-by-step explanation:

6(x+4)+35

B) 6x+ 6(4)+ 35 (They just distributed the 6 to the x but left the 4 undistributed)

C) 35+6(x+4) (If addition or subtraction, moving the numbers won't change the sum/difference)

E) 6(4+x)+35 (If addition or subtraction, moving the numbers won't change the sum/difference)

answer: (1,3) and (-2,0) i think.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
