Answer:
3w³ + 20w² + 39w + 18
Step-by-step explanation:
It is given that,
(2 + 3w)(w² + 6w + 9)
<u>To find the multiplication</u>
(2 + 3w)(w² + 6w + 9) = 2 * w² + 2 * 6w + 2* 9 + 3w * w² +3w * 6w + 3w* 9
= 2w² + 12w + 18 + 3w³ + 18w² + 27w
= 3w³ + 20w² + 39w + 18
Therefore the final value = 3w³ + 20w² + 39w + 18
Answer:
The bus drives 84 miles
Step-by-step explanation:
The question relates to relationship between average speed and time
The given parameters are;
The time duration in which the bus drives = 3/2 hours = 1.5 hours
The average speed of the bus = 56 mph
The formula average speed is given as follows;
Therefore, we have;
The total distance driven = Average speed × The time duration of travel
The total distance driven = The distance the bus drives
Substituting the given values, gives;
The distance the bus drives = 56 miles/hour × 1.5 hours = 84 miles
The distance the bus drives = 84 miles.
