What is the length, in units, of the line segment with endpoints at (1, 4) and (3, 7)?
answer are
15 squared
52 squared
5 squared
and 137 squared

The length in units of the line segment with endpoints at (1, 4) and (3, 7)   is √13   units

Step-by-step explanation:

To find the length of the line segment, we will follow the steps below;

first, write down the distance  formula

Let A=(1,4)   and B=(3,7)

AB = √(x₂-x₁)²  +  (y₂-y₁)²

From the question given, the point given are (1,4)   and  (3,7), this implies that

x₁  =1              y₁ =4                           x₂  =3               y₂=7

Lets insert the values into the formula;

AB = √(x₂-x₁)²  +  (y₂-y₁)²

AB = √(3-1)²  +  (7-4)²

        =√2²  +  3²

       =√4 +   9

         =√13   units

The length in units of the line segment with endpoints at (1, 4) and (3, 7)   is √13   units

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
