54.
3^2 = 3 x 3, which equals 9.
Multiply 9 by 6, which gives the answer of 54
A^2 -121 = a^2 -11^2 = (a-11)(a+11)
so the second choice is right sure
Answer:
I believe the answer is 80 meters.
Note: I am not sure how to explain this so that it makes sense.
He now has 44 so subtract 17 from that and you get 27 (1/2 of the number of his original stamp collection). Then add 27 +27 and you get 54. I believe 54 is the answer. Hope that helps!
