Answer:
I think the answer is 2x^2+5x−8
Step-by-step explanation:
The following classification of <em>quadratic</em> equations is presented below:
- x = - 2 and x = 3: h(x) = (x + 2) · (x - 3), k(x) = - 3 · (x + 2) · (x - 3).
- x = 2 and x = - 3: g(x) = 8 · (x + 3) · (x - 2), m(x) = (x + 3) · (x - 2).
- Neither: j(x) = (x - 2) · (x - 3)
<h3>How to classify quadratic equations in terms of its roots</h3>
In this problem we have <em>quadratic</em> equations in <em>factored</em> form, whose form is presented below:
y = a · (x - r₁) · (x - r₂) (1)
Where r₁ and r₂ are the roots of the equation and a is the <em>leading</em> coefficient. A value of x is a root if and only if y is zero. Besides, we must located all the <em>quadratic</em> equations according to their roots.
x = - 2 and x = 3
h(x) = (x + 2) · (x - 3)
k(x) = - 3 · (x + 2) · (x - 3)
x = 2 and x = - 3
g(x) = 8 · (x + 3) · (x - 2)
m(x) = (x + 3) · (x - 2)
Neither
f(x) = 3 · (x - 1) · (x + 2)
j(x) = (x - 2) · (x - 3)

Answer:
4650 adults
Step-by-step explanation:
The ratio of people who drink coffee to total people is 31/50, or 0.62
To find the number of adults in the town who drink coffee, multiply the ratio by how many people there are in the town.
Plugging in the values we are given,
0.62 * 7500 = 4650
We can expect 4650 adults to drink coffee in the town.
