sqrt157~~12.53" to 2 dec. places"√157≈12.53 to 2 dec. places

Explanation:

"calculate the distance d using the "color(blue)"distance formula"calculate the distance d using the distance formula

•color(white)(x)d=sqrt((x_2-x_1)^2+(y_2-y_1)^2)∙xd=√(x2−x1)2+(y2−y1)2

"let "(x_1,y_1)=(-3,0)" and "(x_2,y_2)=(8,-6)let (x1,y1)=(−3,0) and (x2,y2)=(8,−6)

d=sqrt((8-(-3))^2+(-6-0)^2)d=√(8−(−3))2+(−6−0)2

color(white)(d)=sqrt(11^2+6^2)=sqrt157~~12.53d=√112+62=√157≈12.53
