Answer:
√116 (or 10.77)
Step-by-step explanation:
(refer to attached )
in this case the points given are (-4,-3) and (-8,7)
hence x1 = -4, y1 = -3, x2 = -8, y2 = 7
D = √[ (x2-x1)² + (y2-y1)² ]
= √[ ( -8 - (-4) )² + ( 7 - (-3) )² ]
= √[ ( -8 +4 )² + ( 7 + 3 )² ]
= √[ ( -4 )² + ( 10 )² ]
= √[ ( 16 ) + ( 100 ) ]
= √116
= 10.77

Answer:
9 white ribbons were awarded
Step-by-step explanation:
make white x
make blue b and make red r
b=x-1
r=x+3
w=x
add them up
x-1+x+3+x=29
x-1 +x+3 is 2x+2
2x+2+x=29
3x+2=29
subtract 2 on both sides
3x=27
divide by 2
x=9
Answer:
