Well there both even numbers so the gcf factor would have to be even also
60 = 1,2,3,4,5,6,10,12,15,20,30,60
72 = 1,2,3,4,6,8,9,12,18,24,36,72
The Gcf would be 12
Well the sum is 15+6=21. then you must do 81-21=60. So your answer must be t=60.
Answer:
26
Step-by-step explanation:
Thus, f(b)−f(a)b−a=3(4)−(3(1))4−(1)=26.
