ten point seven seven

thirteen point zero four

sixteen point one two

Answer 1

twelve point zero eight

Answer 2

u sure?

Answer 3

yeah .
pythagoras

sqrt[ (change in x)^2 + (change in y)^2]

= sqrt[((-6)-(5))^2 +((-4)-((-9))^2]
= sqrt[(-11)^2 + 5^2]
= sqrt[121+25] = sqrt[146]
since sqrt[144] = 12 and sqrt[146] is slightly more then the answer will be Answer D

Answer 4
