What percentage of adults in high‑income countries are overweight or obese? (Enter you answer rounded to one decimal place.)

66%

Step-by-step explanation:

According to a study conducted by the World Health Organization, 66% of adults in high-income countries are overweight. Even though the exact reason for this is not known, there are two main theories. The first one is that individuals make more money and therefore have extra income to spend on food, mainly junk food such as snacks, ice cream, candy, etc. The second theory is that due to the large number of work hours that individuals in these countries have to put in, they tend to eat more often at fast food places such as McDonald's and Burgerking.

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
