Answer:
Third one is correct because it says it must be more than 2 not 2 or more.
The one you choose would be like, it must be 2 or more.
Step-by-step explanation:
If an is a5
and
an-1 is a4
then using your recursive formula for an arithmetic sequence
an=an-1 +d
then
a5=a4+d
now, a4 =6 and common difference "d" is d=-11
hence
a5=6 -11
6-11= -5
any questions?
Answer:
what is this supposed to mean??
Step-by-step explanation:
The Last on = 45x^2 - 2x - 8
Reason being is because you would group and multiple:
(9x - 4) • (5x +2)
(x + 5) * (x − 5) =
x² - 25
----------------
x * x = x² and 5 * (-5) = -25
