Eiffel tower: the travel guide says that the tower is 324m tall. as an american who measures
height in feet, this fact does not mean much to you. comparing the tower to a familiar building
would you better understand the height. which american building is closest to the eiffel
tower in height? | 1 foot = (3048meters
1. washington monument-555 feet
2. chrysler building, nyc-1,050 feet
3. sear tower, chicago-1,729 feet

  or  

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

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

4+3x is the answer

hope you got it
