I think it’s line graph but I think I’m completely wrong-
Answer:(-8,-4)
Step-by-step explanation:
Find the intersection point between the 2 restraint equations:

Substitute back in to find y-value:

P is maximized at point (12,6)
The answer is 221.1 cubic inches
Using the equation V=lwh, and plugging in the numbers, you would get your answer of 221.1 cubic inches
V=lwh
V=16 3/4 x 3 x 4 2/5
V=221.1 cubic inches
