so many homework questions, and not enough time to do them ;)

anonymous · Answer

im am doing them , i just need more help on these.

anonymous · Answer

$$\sqrt{(-2-(-7)^2+(-3-(-8))^2}$$
$$\sqrt{5^2+5^2}$$
$$\sqrt{50}$$

amistre64 · Answer

i like to stack the points; makes subtracting them easier

anonymous · Answer

i get 7.07 rounds to 7.1

amistre64 · Answer

( -2, -3)
-(-7, -8)

 ( -2, -3)
  ( 7,  8)
---------
    (5,5)

sqrt(5^2 + 5^2) = sqrt(50) = sqrt(2*25) = 5sqrt(2)

anonymous · Answer

another embarrassment frankly since it is really 
$$5\sqrt{2}$$ as you have the diagonal of a square with side 5!
