25-(2+5)(2+5)
25- 4+10+10+25
=66
The pattern is dividing by 2.
512, 256, 128, 64
512/2 = 256, 256/2 = 128, 128/2 = 64
64/2 = 32, 32/2 = 16, 16/2 = 8, 8/2 = 4, 4/2 = 2, ...
Answer:
75
Step-by-step explanation: Well, since you didn't say what fiction was, I have no way to confirm this, but if 36, 20, and 30 add up to 86, and I use 36 (comedy) and multiply it by the amount of students serveyed, I get 5,400. Devide that by 86 (the total of all servey) You get 62, and again, since I don't have the percent for fiction, I will have to say that it is most likely 75, due to that being the only number above 62.
It would be 3h(3h^2 -4), it is factored
