12 x 2 = 24 (Julio), 24 x 4 = 96 (David).
Answer:
If using complex numbers, or undefined if using all real numbers
Step-by-step explanation:
Moving -8 to the left side of the eq by adding both sides by 8=
x^2-3x+8=0
The quad formula:
a=1 b=-3 c=8
Inserting a b c values into formula: 
Simplifying:
Since the square root of a negative number doesn't exist in the set of real numbers, the equation is undefined.
OR
Using complex numbers i, to replace the negative number created by subtracting 9-32.
5/6. There are six sides, 3 is one of them. The probability of it not being 3 is all of the other faces.
Answer:
480
Step-by-step explanation:
Original Price = o = 400
% increase in price = i = 20% = 0.20
New Price = n = ?
n = o + (o x i)
n = 400 + (400 x 0.20)
n = 400 + 80
n = 480
Hence the new price is 480
Answer:
about 20 feet
Step-by-step explanation:
This is basically a circumference problem. We want to know the distance her toe travels every circle, which is the outside of the circle, so we solve for circumference.
C = 2πr
The radius is her leg! r = 3.2 feet
C = 2π(3.2)
= 20.106 ≈ 20 feet
