Answer:
AC and BD are vertically oposite
and both sides are equal (equilateral) so AC = BD
As i think
Scale Factor (K) = (new length/measure)/ (original length/measure)
for x-coordinate = 8/2 = 4
for y-coordinate = 16/4 = 4
K=4, expansion
K is the representation of "scale factor". Scale factor is the ratio of the lengths involved of the similar figures. It can be used to identify the kind of dilation, whether it is contraction or expansion. If the Scale Factor is greater than 1, then that means expansion and if it is less than 1, then it signifies contraction.
Answer:
600
Step-by-step explanation:
Because the tens digit is less than 5, round down to 600
5: 11.97
6: 4.1
7: 14.484
8: 12.34
Hope this helps!
