Question

A (1,7) B(8,-5) distance formula

Answer 1

Answer:

The distance betweem the two points is about 14

Step-by-step explanation:

The distance formula is $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

According to the problem: $x_{2}=8$, $x_{1} =1$, $y_{2} =-5$, and $y_{1} =7$

Substitute these numbers into the problem to get $d=\sqrt{(8-1)^{2}+(-5-7)^{2}}$

$(8-1)^2=(7)^2=49$

$(-5-7)^2=(-12)^2=144$

$\sqrt{49+144}=\sqrt{193} =13.8923349894$

You can round this number to approximately 14.
