Question<br> Find the distance between the points (-5, 8) and (-3,0).
Temka [501]

To calculate the distance between two points we use this formula:

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

<h3>______________________</h3>

<h3>We organize the values:</h3>

  • x₁ = -5
  • x₂ = -3
  • y₁ = 8
  • y₂ = 0

______________________

We apply the values already obtained to the formula to get the distance:

d \:  =   \:  \sqrt{( - 3 \:  -  \:( - 5))^{2} \:  +  \: (0 \:  -  \: 8)^{2} }

d \:  =   \:  \sqrt{( - 3 \:  -  \: ( - 5))^{2} \:  +  \: ( - 8)^{2} }

d \:  =  \:  \sqrt{( - 3 \:  +  \: 5) ^{2}  \:  +  \: 64 }

d \:  =  \:  \sqrt{ {2}^{2} \:  +  \: 64 }

d \:  =  \:  \sqrt{4 \:  +  \: 64}

d \:  =  \:  \sqrt{68}

d \:  = \boxed{ \bold{  \: 2 \sqrt{17}  \:   units}}

<h2>Answer: </h2>

\huge{\boxed{ \bold{2 \sqrt{17} \: units }}}
