Answer:
{x| 43 ≤ x ≤ 47} where x = Sean's speed (in mph)
Step-by-step explanation:
Sean is taking driver's ed. The instructor asked him to stay within 2 miles of the posted speed limits. The current speed limit is 45 mph.
So, the maximum speed which Sean can reach is, (45 + 2) mph
=47 mph
and, the minimum speed which Sean can reach is, (45 - 2) mph
=43 mph
so, {x| 43 ≤ x ≤ 47} where x = Sean's speed (in mph)
why do they be giving us this hardwork :(

Step-by-step explanation:
We know that,
1 m = 100 cm
the conversion from m² to cm² is as follows :
(1 m)² = (100 cm)² = 10000 cm²
A conversion factor between cubic meters and cubic centimeters is as follows :
(1 cm)³ = (100 cm)³
= 1000000 cm³
To convert m³ to cm³, multiply by 1000000.
Hence, this is the required solution.
