Answer:
Y'=3xy-3x-12
Y'=F(-2,-1)=0
Step-by-step explanation:
The function of the equation at the point (-2,-1)
is where the equation make the function go to zero:
Y'=3xy-3x-12
Y'=F(-2,-1)=[3(-2)(-1)]-[3(-1)]-12
F(-2,-1)=[6]-[-6]-12
F(-2,-1)=6+6-12
F(-2,-1)=12-12
F(-2,-1)=0
Solving for y
3xy-3x-12=0
y=4/x+x
Making y=0
So the values make the function go to zero
Area of the entire rectangle
Solution:
Area of the blue box = length × width
Area of the blue box
Area of the pink box = length × width
Area of the pink box
Area of the green box = length × width
Area of the green box
Area of the orange box = length × width
Area of the orange box = 24
Total area of the rectangle
