Question

Clint is trying to calculate the distance between point G(13, 2) and point H(1, 7). Which of the following expressions will he use?

Answer 1

This sounds like a multiple choice question and I do not know the options, but to find the distance use pythagorean theorem.
`a^(2) +b ^(2) =c ^(2)`

Answer 2

square root of the quantity of
`7` minus
`2` all squared plus
`1` minus
`13` all squared

Explanation:

we know that

the formula to calculate the distance between two points is equal to

`d=\sqrt{(y2-y1)^(2)+(x2-x1)^(2)}`

we have

`G(13,2)\\H(1,7)`

substitute the values

`d=\sqrt{(7-2)^(2)+(1-13)^(2)}` -----> this is the expression

`d=\sqrt{(5)^(2)+(-12)^(2)}`

`d=√(169)\ units`

`dGH=13\ units`
