3. 6/3 equals 2 and 9 divided by 3 equals 3, so a simplified expresssion would say (2n^2)-3.
Lowest to highest in order:
-10, -2, 0, 3, 4, 6
Answer:
Mandy will take 67.5 mins to complete the 15 km race.
Step-by-step explanation:
Given:
Mandy runs 4 km in 18 min
She plans to run in a 15 km race.
We need to find how much time required to run 15 km.
4 km =18 min
15 km = time required for 15 km race
By Using Unitary method we get,
Time required for 15 km = 
Hence time required by Mandy to complete 15 km race is 67.5 mins.
First 5 terms are: -1,0,3,8,15
Step-by-step explanation:
we will put n=1,2,3,4,5 to find first 5 terms of the sequence
Explicit formula for sequence is:

Putting n=1

Putting n=2

Putting n=3

Putting n=4

Putting n=5

Hence,
First 5 terms are: -1,0,3,8,15
