Answer:
2
Step-by-step explanation:
No.
1/4 would be proportional to 9/36.
8/36 can be simplified to 4/18, and further reduced to 2/9.
Use a proportion.
2 adults to 18 students is as x adults to 99 students.
2/18 = x/99
18x = 2 * 99
18x = 198
x = 11
Answer: 11 adults
It's quadratic
(3x+4)(-2x-3)
expand using FOIL:
-6x^2-14x-12=0
remember -6x^2 term means its quadratic since it's powered by 2
