Answer:
D. (y-4)^2/12^2 + (x-2)^2/6^2=1
Step-by-step explanation:
Took the quiz.
Factors of 80: 1,2,4,5,8,10,16,20,40,80
so we cross out 1,2,4,5,8,10,16
the first 5 multiples of 3 are: 3,6,9,12,15
so we cross out those number and then we are left with 7, 11, 13 and 14
the answer is: 4 numbers were not crossed out
