Answer:
The shape is translated four units left, and 2 units up, therefore the answer would be x=-4 and y=+2
2 * (2a + b) + 8 = 4a + 2b + 8
------------------------------------------
A. =
B. =
C. ≠ 4* (a + b + 2) = 4a + 4b + 8
D. =
A rational expression is undefined when the denominator is zero.

is undefined when x=0 or x=2.
Answer:
1) 78.54
2) 490.87
3) diameter: 15.9999 so 16.00? circumference: 50.27
Step-by-step explanation:
If you would like to solve p = r - c for c, you can do this using the following steps:
p = r - c /+c
p + c = r - c + c
p + c = r /-p
p + c - p = r - p
c = r - p
The correct result would be c = r - p.
