Answer:

<h2>The answer is 5 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

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

where

(x1 , y1) and (x2 , y2) are the points

From the question

The points are (9,-7) and (5, -4)

The distance between them is

d =  \sqrt{ ({9 - 5})^{2} +  ({ - 7 + 4})^{2}  }  \\  =  \sqrt{ {4}^{2}  +  ({ - 3})^{2} }  \\  =  \sqrt{16 + 9}  \\  =  \sqrt{25}

We have the final answer as

<h3>5 units</h3>

Hope this helps you

AlexFokin [52]

Answer:

18 stickers.

Step-by-step explanation:

Cindy buys 18 more stickers in the start. This results in 13+18= 31 stickers. She then gets five for her birthday. 31+5=36 so she now has 36 stickers but she then gives eight away which means she has 36-8=28 stickers. She uses ten stickers to decorate so Cindy has 28-10=18 stickers left
