Step-by-step explanation:
14 pizzas.
First, add up the numbers of players on each team and the coachesto get the total number of people eating.
17 + 21 + 20 + 17 + 9 = 84
Then, you can divide 84 by 6 to see how many pizzas: 84/6 = 14
If you’re teacher wants you to set it up as a ratio, it’s 6/1 = 84/x
Then you cross-multiply:
6x = 84
Divide both sides by 6
x = 14
-3x^4 + 27x^2 + 1200 = 0
factor out -3
-3(x^4 -9x^2 -400)=0
divide by -3
x^4 -9x^2 -400=0
(x^2-25) (x^+16) = 0
x^2-25=0 x^2+16=0
(x-5)(x+5)=0 x^2=-16
x=5 x=-5 x = 4i x=-4i
Answer: x=5 x=-5 x = 4i x=-4i
