The answer to your question is 17/18
The answer to this question is A
Answer: 12
Explaining: 2 times 4 is 8 so makes it reasonable to say 3 times 4 is 12. Also both of the triangles are similar just the left is smaller and the right is larger.
Answer:
The first one is the answer.
Step-by-step explanation:
It's an arithmetic sequence. It has a common difference.
d = an - a_n-1
an = -12x + 12
a_n-1 = - 7x + 8
d = -12x + 12 - (-7x + 8)
d = -12x + 12 + 7x - 8
d = -5x + 4
Try it. Let's try for the third term
-12x + 12 - 5x + 4
- 17x + 15 which is exactly what the third term is.
