Answer:
C) 12 pi
Step-by-step explanation:
Circumference = 2 times pi times radius
so, C = 2 x pi x 6 = 12 pi
The answerer is combining terms in x with constants
that is, 13x + 5 ≠ 18x
13x + 5 + 17x - 4.5 + x
= (13x + 17x + x ) + 5 - 4.5 ← collecting like terms
= 31x + 0.5 ← correct simplification
$69.50
.60 + .60 + .60 + .60 + .60 = 3
72.50 - 3 = $69.50
