Answer:

The distance is 19\ units

Step-by-step explanation:

The formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

In this problem

Let

Subway\ Stop(7,-6)\\House(-9,5)  

substitute the values

d=\sqrt{(5+6)^{2}+(-9-7)^{2}}

d=\sqrt{(11)^{2}+(-16)^{2}}

d=\sqrt{377}\ units

d=19\ units

Which model represents the factors of 4x^2-9
dsp73

The model (x+a)(x-a) will represents the factors of 4x²-9 as (2x+3)(2x-3).

<h3>What are the quadratic equations in one variable completing the squares method?</h3>

The "completing the squares" method aims to construct a quadratic equation of the form where the x variable is entirely covered by a single squared term, which is the square of a linear expression in x, as the name suggests.

The quadratic equation can resemble this:

x²-a² = (x+a)(x-a)

Given equation;

⇒4x²-9

⇒(2x)²-3²

The equation can be modeled as;

(2x+3)(2x-3)

Hence the model (x+a)(x-b) will represents the factors of 4x²-9 as (2x+3)(2x-3).
