Yes you did, congratulations ;-)
Answer:
12
Step-by-step explanation:
(6)² = 3x
then x= 36/3
x= 12

so hmmm then we know the slope of that line is -2/3, so we're really looking for the point-slope form of a line with a slope of -2/3 and that passes through (-3 , 8)

Answer:
The answer is 8.
Step-by-step explanation:
The scale factor between the figures is 2/3, this means that the ratio of the smaller figure to the larger figure is 2/3:
.
So when a side of the the larger figure is 12 then:

Therefore
.
Thus the length of the corresponding smaller side is 8.
