Find the distance (-4,5) and (7,18)

Answers

Answer:

√(290)\ units

Step-by-step explanation:

The distance between points (x_1,y_1) and (x_2,y_2) is

√((x_1-x_2)^2+(y_1-y_2)^2)

Hence, the distance between points (-4,5) and (7,18) is

√((-4-7)^2+(5-18)^2)\n \n=√((-11)^2+(-13)^2)\n \n=√(121+169)\n \n=√(290)\ units
