Step-by-step explanation:
[0,7)
because the dot is colored in you need to have the bracket
Answer:
A) 0.50x +300 < 650, where x < 700
(Please mark brainliest. :3)
is there a picture or equation that you can provide ?
I think it’s the maximum number of solutions is one
Suppose the length of the triangle is x, if the perimeter of the rectangle is 100 ft, the width of the rectangle will be (50-x) ft.
Area of rectangle will be:
A=length*width
A=x(50-x)
A=50x-x^2
at maximum area, dA/dx=0
thus
dA/dx=50-2x=0
solving for x we get
2x=50
x=25
thus for maximum area length=25 ft
the size of the width will be
50-x=50-25=25 ft
thus the maximum area will be:
25*25=625 sq. feet
