Answer:

#sqrt41≈6.403" to 3 decimal places"#

Explanation:

#color(red)(bar(ul(|color(white)(2/2)color(black)(d=sqrt((x_2-x_1)^2+(y_2-y_1)^2))color(white)(2/2)|)))larr" distance formula"#
where # (x_1,y_1),(x_2,y_2)" are 2 coordinate points"#

The 2 points here are (-7 ,-4) and (-2 ,0)

let # (x_1,y_1)=(-7,-4)" and " (x_2,y_2)=(-2,0)#

#d=sqrt((-2-(-7))^2+(0-(-4))^2)=sqrt(5^2+4^2)#

#=sqrt(25+16)=sqrt41≈6.403" to 3 decimal places"#
