Answer:
Step-by-step explanation:
x = number of cars
12x = 3.50x + 34
12x - 3.50x = 34
8.5x = 34
x = 34/8.5
x = 4 <=====he would have to sell 4 cars
15.08 m
The angle XZW :
XZW + 108° = 180°
XZW = 180° - 108°
XZW = 72°
Length of an arc = θ / 360 * πd
d = diameter = XV = 24
Length of arc XW = (72/360) * π * 24
Length of arc XW = 15.0796
Length of XW = 15.08 m
