A. 
Answer:
Solution given:

we know that
product of power and power is added and power to power is multiplied for same base only.
I.E.
product of same base but different power:
power to power :
By using above property


![2^{[6+6]}=2^{12}](https://tex.z-dn.net/?f=2%5E%7B%5B6%2B6%5D%7D%3D2%5E%7B12%7D)
12.5% because you divide the two and get 0.125 then to convert it to a percent multiply by 100 for get 12.5%
Answer:
153.8 I guess... this is your answer
Answer:
see the explanation
Step-by-step explanation:
we know that
If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image
If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image
so
<u><em>Verify each value</em></u>
1) -4


therefore
The dilation produces an expansion of the original image
2) 0.25


therefore
The dilation produces a contraction of the original image
3) -2/3


therefore
The dilation produces a contraction of the original image
4) 2.3


therefore
The dilation produces an expansion of the original image
