Question

Find the distance between ( 9,18) and (21,18) in coordinate grid

Answer 1

Answer:

12

Step-by-step explanation:

Use the formula

$\sqrt{(x^2-x^1)^2 +(y^2-y^1)^2$

Input the numbers

21 - 9 = 12

12^2 = 144

18 - 18 = 0

0 ^ 2 = 0

$\sqrt{144}$ = 12

Answer 2

| 9 - 21 |

| -12 |

The distance between (9,18) and (21,18) is 12.
