Answer: ABC is congruent to A’B’C because yo can nap ABC to A’B’C using a rotation of 180 degrees about the origin, which is A rigid motion
S = 4pi r^2
S/4pi = r^2
taking square root on both sides,
r = sqrt (S/4pi)

Answer:
w = -z(-w) + 3(-w)
Step-by-step explanation:
z = w + 3 | Given
-w + z = 3 | Subtract w from both sides.
-w = -z + 3 | Subtract z from both sides
w = -z(-w) + 3(-w) | Multiply -w on both sides.
Answer: 2(34) + 2c = 98
Step-by-step explanation:
C = cost of one canteen
2 pair of boots at $ 34 each plus 2 canteens at (c) each totals $98.
2(34) + 2c = 98
68 +2c = 98. Subtract 68 from both sides. 68 - 68 +2c = 98 -68
2c = 30. Divide both sides by 2.
2c/2 = 30/2
c = 15 so each canteen costs $15
Check: 2 ($34) + 2 ($15) = $98
$68 + $30 = $98
$98 = $98
2C = 98
