The multiplication of the expression ( 2n + 2 )( 6n + 1 ) is 12n² + 14n + 2.
What is the simplified form of the given expression?
Given the expression in the question:
( 2n + 2 )( 6n + 1 )
To multiply the expression ( 2n + 2 )( 6n + 1 ), we use the distributive property and the FOIL method.
( 2n + 2 )( 6n + 1 )
Using the Foil method:
2n( 6n + 1 ) + 2( 6n + 1 )
Using the distributive property:
2n × 6n + 2 × 1 + 2 × 6n + 2 × 1
Multiplying, we get:
12n² + 2n + 12n + 2
Collect and add the like terms:
12n² + 14n + 2
Therefore, the simplified form is 12n² + 14n + 2.

Answer:
To find the winner's average speed in meters per hour, you can first convert the kilometers to meters and the hours to seconds. Then, divide the distance by the time.
1 kilometer = 1000 meters
1 hour = 3600 seconds
So, the distance in meters is:
3391.1 kilometers * 1000 meters/kilometer = 3,391,100 meters
And the time in seconds is:
83.5 hours * 3600 seconds/hour = 300,600 seconds
Now, calculate the average speed:
Average Speed = Distance / Time
Average Speed = 3,391,100 meters / 300,600 seconds
Average Speed ≈ 11.28 meters per second
To convert this to meters per hour:
11.28 meters per second * 3600 seconds/hour ≈ 40,608 meters per hour
So, the winner's average speed in meters per hour was approximately 40,608 meters per hour.

$0.60 bottle of iced tea marked up to $1.35. Find the percentage markup.
Answer:
percentage markup = 125%
Step-by-step explanation:
$0.60 bottle of iced tea marked up to $1.35. The marked up percentage can be calculated as follows:
1.35/0.60 = p/100
2.25 = p/100
2.25 = p/100
multiply both sides by 100
2.25 × 100 = p
225%
Therefore the mark up is 225 - 100 = 125%
percentage markup = 125%
