Answer:
I think it would be 4×n-3 = n+12
Answer:
(x+3)(x-3) is x²-9
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
120/360 = 12/36 = 2/6 = 1/3
Answer:
First term = -41.
Common difference = -15.
Step-by-step explanation:
nth term: an = a1 + (n - 1)d where a = first term and d = the common difference.
-671 = a1 + (43 - 1)d
-806 = a1 +(52 - 1)d
-671 = a1 + 42d
-806 = a1 + 51d
Subtracting ( to eliminate a1):
-671 - (-806) = 42d - 51d
-9d = 135
d = -15
Substitute for d in the first equation:
-671 = a1 + 42*-15
-671 = a1 - 630
a1 = -671 + 630 = -41.
It’s A because 3 8’s are 24 but it’s not a mulitiple of 12
