Just plug in 3 for n and then 5 for n to see if an turns out to be 10 and 26.
n=3:
A) an = 8*3+10 = 34
B) an = 8*3 - 14 = 10 OK
C) an = 16*3+10 = 58
D) an = 16*3 - 38 = 10 OK
n=5:
B) an = 8*5-14 = 26 OK
D) an = 16*5 - 38 = 42
So the answer is B
A. 36, the reason being is because 18x 2 is 36 and 12 x 3 is 36
I honestly don’t know
Sorry sweety
-6 = -3x -12
6 = -3x
x = -2
y = -3(-2) -12
y = 6 -12
y = -6
(-2,-6)
