What is the rate for 60lbs and $5

The rate is for 12lbs, it equals $1.

You have to divide 60 by 5, and that gives you 12.

12lbs = $1.

24lbs = $2

36lbs = $3

48lbs = $4

60lbs = $5

step-by-step explanation:

for volume, add base x height x width

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
