Answer:

x² - 3x - 10 = 0

Step-by-step explanation:

Given there are 2 solutions then the equation is a quadratic.

Since the solutions are x = - 2 and x = 5 then

the factors are (x + 2) and (x - 5) and

f(x) = (x + 2)(x - 5) ← expand factors

= x² - 3x - 10, hence the equation is

x² - 3x - 10 = 0

There are three hallways at Wilson Middle School, as represented in the coordinate plane below. Four points are plotted on the c

kupik [55]

The total length is 226.59 units. The flagpole is at (78,75)

Step-by-step explanation:

To find the distance between two points given the coordinates apply the formula for distance as;

$d=\sqrt{(y_2-y_1)^2+ (x_2-x_1)^2}$

For segment ;

AB, A(-20,60) and B(-20,-25)

$d=\sqrt{(-25-60)^2} \\\\d=\sqrt{(-85)^2} \\\\d=85$

For segment AD

A(-20,60) and D(50,75)

$d=\sqrt{(75-60)^2+(50--20)^2} \\\\d=\sqrt{(15)^2+(70)^2} \\\\d=\sqrt{5125} \\\\d=71.59$

For segment

B(-20,-25) and C(50,-25)

$d=\sqrt{(50--20)^2} \\\\d=\sqrt{70^2} \\\\d=70$

Total length of the three hallways is 85+71.59+70 =226.59 units

PART B

The flagpole is 28 meters to the right of point D

Point D(50,75)

Flagpole will be (50+28,75), = (78,75)
