Answer:
6
Step-by-step explanation:
If you divide 4/5 divided by 1/8 you get 6.4. Therefore, you can only make 6 full burgers.
a3+b3=(a+b)(a2-ab+b2)
a₁ = 1
r = 3
Since it’s a geometric series then
a₁ = 1 ( because 1 is the first term of the series)
3/1 = 9/3 = 27/9 = 81/27 = 3 then r=3.
the answer to your question is
2n + 20
