Answer:
3. 33
4. g(x) = 3 (1+n)
Explanation:
For the equation, I am not entirely sure that is what your teacher is looking for, but it definitely works! : )
To make it I just said that it looked like there were three different equal parts to the figures, and the area of the parts increases by one every time. So I just added 1 to whatever number it is which gets the area of one of the parts, and multiplied it by 3!
For number 3, I just plugged it into the equation I just made.
g(x) = 3(1+(10))
= 3(11)
= 33
