Explanation:
#"using the 3-dimensional form of the "color(blue)"distance formula"#
#•color(white)(x)d=sqrt((x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2)#
#"let "(x_1,y_1,z_1)=(10,15,-2)" and "#
#(x_2,y_2,z_2)=(12,-2,15)#
#d=sqrt((12-10)^2+(-2-15)^2+(15+2)^2)#
#color(white)(d)=sqrt(4+289+289)=sqrt582~~24.12#
