Answer:

The numbers are 4 and 5

Step-by-step explanation:

Let

x------> the smaller number

x+1----> the bigger number

we know that

\sqrt{x}=(x+1)-3 ----> equation that represent the situation

solve for x

\sqrt{x}=(x-2)

squared both sides

x=(x-2)^{2}\\x=x^{2}-4x+4\\x^{2}-5x+4=0

using a graphing calculator to solve the quadratic equation

see the attached figure

the solution is

x=4

x+1=5

Step-by-step explanation:

Para ampliar la habitación cuadrada, se agregaron 4 metros de largo y 2 metros de ancho, como se muestra en la figura.

Determine the slope of each line.
faust18 [17]
(2,-2)(5,7)

7-(-2)= 9
5-2= 3
9/3= 3

slope = 3

(you could also calculate the slope by just counting up how many units it goes up/down when you pick a point from the x-axis and move left/right. basically counting the rise over run)
