take a factor of 6 out to make 6(4x-3)
Answer:
11 yard
Step-by-step explanation:
Let the 3rd side be 'a'.
Perimeter = 36
=> sum of sides = 36
=> 10 + 15 + a = 36
=> 25 + a = 36
=> a = 36 - 25
=> a = 11
To find the mean, add all the numbers together and divide by the amount of numbers there are
There are 5 numbers in this case.
(97 + 45 + 92 + 15 + 89)/5
338/5 = 67.6
67.6 is your answer
hope this helps :D
