Let's assume
length of Ribbon A is A
length of Ribbon B is B
length of Ribbon C is C
we are given
A=B+20% of B
A=1.2B
B=C-20% of C
B=0.80C
now, we can find relation between A and C
A=1.2B
we can plug B
A=1.2*0.80C
A=0.96C
so,
Ribbon A is 4 % shorter than Ribbon C.......Answer
from the graph we can see that the vertex is at h = -2 and k = - 4, we also know that the parabola runs through the point (-1 , 0)

Answer:
-2
Step-by-step explanation:
Subtracting a negative number is the same as adding it, so this is basically just negative 8 plus 6, which is -2. Don't know who was right though, you kinda left that part of the question out.
