Answer:
B
Step-by-step explanation:
The distance formula is sqrt((x1-x2)^2 + (y1-y2)^2), therefore (3-(-6))^2 = 9^2 and (5 -(-6))^2 = 11^2 so 121 + 81 = sqrt(202), this converted to decimal is ~14.21, so D.
8/15 - (-2/3)
Its like adding them when its -(-#), so we turn it into 8/15 + 2/3
Now we make each fraction have the same denominator; 8/15 + 10/15
Now we solve by adding; 18/15 = 1 1/5
It is $57.38 you just multiply it by 1.00 and you get $57.38.
