14x - 129 (I think I’m so sorry if it’s wrong)
Answer:
8n³ + 4
Step-by-step explanation:
Sometimes it will, and sometimes it won't.

I'm not sure if you would count these, but x and y also have the intercept of (0,0).
We can find h by calculating the area S of the parallelogram in two ways. We can write:
. On the other hand,
. Then:
