The distance AB rounded to the nearest tenth =
Whitepunk [10]

it gives you the formula, so all you have to do is plug in the coordinates

d =  \sqrt{ {( - 1 + 3)}^{2} +  {( - 1 - 1)}^{2}  }  \\ d =  \sqrt{ {(2)}^{2} +  {( - 2)}^{2}  } \\ d =  \sqrt{ 4 +  4  } \\ d =  \sqrt{8} \\ d = 2 \sqrt{3}  = 3.4641... \\  \\ d = 3.5

3/4h-9=1/4h-1 i need help
Vlada [557]

<u> Answer I got for this was 16.

Subtract the 1/4 from the 3/4 and get 2/4, simplified: 1/2

You should have 1/2 h -9 = -1 by now,
Then add nine to the other side, getting 8.
You should have 1/2 h = 8.
Then divide 1/2 by 8.
8/1÷1/2 ---> 8/1 × 2/1 (you flip the fraction when you divide)
So your answer is 16!
Hopefully that helped!</u>
