Answer:
In two similar geometric figures, the ratio of their corresponding sides is called the scale factor.
To find the scale factor,we need to follow some rules:
locate two corresponding sides, one on each figure.
Write the ratio of one length to the other to find the scale factor from one figure to the other
Answer:
Option D. two complex roots
Step-by-step explanation:
we know that
In a quadratic equation of the form 
the discriminant D is equal to
in this problem we have
so
substitute the values
The discriminant is negative
therefore
The quadratic equation has two complex roots
Answer:
6
because when you subtract 6 from 6 you get 0
6 - 6 = 0
V=(4/3)pir^3
4.5pi=(4/3)pir^3
divide both sides by pi
4.5=(4/3)r^3
times 3/4 both sides
3.375=r^3
cube root both sides
1.5=r
radius is 1.5cm
Total: 318
Student tickets: x
Adult tickets: 3x+6
x+(3x+6)=318 -> 4x+6=318 -> 4x=312 -> x=78
3(78)+6 = 234+6 = 240
240 adult tickets were sold
