20. 64% of the people at the movie theater bought popcorn in one weekend. For the next weekend, if the movie theater expects 125 people, then how many should be expected to buy popcorn?

26

Step-by-step explanation:

20.64 divided by 100 then multiplied by 125 which will result in you receiving the answer 25.8 but I rounded it off to 26

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  

its c or d   take a lucky guess my dude
