Harper surveyed every fourth student coming back from lunch in 6th grade to see what sport they preferred to participate in for field day. Out of the 28 students she surveyed, 8 stated that they would prefer to play volleyball. If there are a total of 392 students in 6th grade, how many would you expect to prefer volleyball?"​

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

1/3 + 1/5 = 8/15.

step-by-step explanation:
