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:
9 < √88 < 10
Second one
Step-by-step explanation:
√81 = 9
√100 = 10
√88 is between √81 and √100
so
√81 < √88 < √100
or
9 < √88 < 10
Answer:
-3x-15
Step-by-step explanation:
you use the distributive property. So it would be 3 times -x and 3 times -5 so you get -3x-15.
