Answer:
n=-5
Step-by-step explanation:
6n+4=-26
=>6n=-26-4
=>6n=-30
=>n= -30/6
=>n=-5
B & C I believe, not too sure about the “B” but ik C for sure
Area of a square=x^2
where x=1 side
if x=8 then
8^2=8 times 8=64
answer is 64 square feet
The sequence is geometric. The infinite series does converge.
Note how dividing any given term by the previous one leads to the same result
-8/12 = -2/3
(16/3) divided by -8 = -2/3
and so on...
So the common ratio is r = -2/3. This proves the sequence is geometric.
Since |r| < 1 is true, this means the infinite series converges to some fixed number.<span />
