Answer:
y³ + x³ = 1
First, differentiate the first time, term by term:

↑ we'll substitute this later (4th step onwards)
Differentiate the second time:


Answer:
I'm pretty sure the answer is a
Answer: x^2+29x+39
You would first have to set up an equation, which would be ((2x+9)⋅(x+6))-((x-5)⋅(x-3)) to find the area of both rectangles.
Then you can simplify it, which gives us 2x^2+21x+54-(x^2-8x+15)
Then simplify it even more which gives us 2x^2+21x+54-x^2+8x-15
Then we can get our answer: x^2+29x+39
Hope that helps :)
Answer:
Step-by-step explanation:
(x + 4)/2 = 9
x + 4 = 18
x = 14
(y-2)/2 = 4
y - 2 = 8
y = 10
(14, 10)
