Step-by-step explanation:
Given


Required
Determine the possible number of combinations
The question emphasizes on "selection" which means "combination".
So; To answer this question, we apply the following combination formula:

In this case:


The formula becomes:






<em>Hence, there are 15 possible combinations</em>
The answer is -22 because when you subtract -8 from -14 it gives you -22!
The altitude drawn to the base is the median and the angle bisector.
Answer is true
3 (k-12) = k-30
3k - 36 = k - 30
3k - k = -30 + 36
2k = 6
k = 3
Quotient is n over 7
difference is n-7
product is 7n
sum is n+7
