The simplified expression would be 3s + 15.
In order to find this we need to write an equation for the longest side. Since it's 3 more than twice as much as the smallest side (s), we can express it as 2s + 3. Now we simply add all 3 together and simplify.
2s + 3 + 12 + s -----> simplify
3s + 15
Answer:
Range = 5
Mode = 7
Step-by-step explanation:
To find range we first need to find the highest number and the lowest number
3 , 4 , 4 , 7 , 7 ,7 ,7 7, 8
least number = 3
highest number = 8
now substract the lowest number from the highest to get the range
= 8-3
= 5
range = 5
Mode : the most common number in the list will be our mode
7 is our mode as it came 5 time in the list
