Callie is sending her nephew a soccer ball for his birthday. She packs the ball in a cubic box that has the same side length as the diameter of the ball. She needs to determine how much space needs to
be filled with packing material. (Use 3.14 or the button on your calculator. Round all results to the
nearest hundredth)

step-by-step explanation:

about 168 miles

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

answer: 12/52

step-by-step explanation: my reasoning is that there are 12 face cards in a deck and a total of 52 cards in all.
