2 + 3x = 4 + 2x + x^2
x^2 - x + 2 = 0

(x - 0.5)^2 - 0.25 + 2 = 0

(x - 0.5)^2 = -1.75

x - 0.5 = +/- sqrt 1.75 * i

x = 0.5 + 1.32i  ,  0.5 - 1.32i  answer

Un tubo puede contener 35 l de agua por metro si mide 97 metros ¿Cuanto pesara el agua que contiene al es lleno
Mariana [72]

Respuesta:

3395 L

Question 2 of 10
AnnyKZ [126]

The length of AB will be 10 units. Option B is corect. The formula for the distance between the two points is applied in a given problem.

<h3>What is the distance between the two points?</h3>

The length of the line segment connecting two places is the distance between them.

The distance between two places is always positive, and equal-length segments are referred to as congruent segments.

The given coordinate in the problem is;

(x₁,y₁)=(-2,-4)

(x₂, y₂)= (-8, 4)

The distance between the two points is found as;

\rm d= \sqrt{(-8-(-2))^2+(4-(-4))^2}\\\\ d=10 \ units

Hence, option B is corect.

To learn more about the distance between the two points, refer to;
