A would be equal to 1 since a is equal to one already
Answer:
375 in² is the answer.
Step-by-step explanation:
Are of rectangle= area of 2 triangle
= 1/2*25*15+1/2*25*15
=187.5+187.5
=375 in²
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
5 least common multiple is 5 nines is 3 and thirty's is 3
