C
the sum to infinity of a geometric series = 
where a is the first term and r the common ratio
= 
= 81 × 3 = 243
Answer:
3x^2
Step-by-step explanation:
The missing term is the product of x and 3x.
x * 3x = 3x^2
Answer: 3x^2
Answer:
9;10
Step-by-step explanation:
What we can first do is make them into one double sided inequality and then interpret it from there.
After combining them we get: 7<x<12
This means that any number between 7 and 12 can be picked.
Keep in mind, this means that 7 and 12 cannot be picked, they have to be in between.
Therefore, we get our aswers of 9 and 10!
It’s a function. It passes the vertical line test.
Just plot it and you get something like this ...
