Answer:
dy/dx =
Step-by-step explanation:
-y + 2x²- x = -5y³
2x² - x = y - 5y³
4x - 1 = dy/dx - 15y².dy/dx
dy/dx(1 - 15y²) = 4x - 1
dy/dx =
Let's assume
length of rectangle is L
width of rectangle is W
the width of a rectangle is 3 meters more than one-fourth its length
so,
the perimeter is 10 meters more than twice its length
we know that
perimeter =2(L+W)
so, we get
now, we can simplify it
subtract both sides by 2L
now, we can find L
subtract both sides 3
multiply both sides by 4
so,
length of rectangle is 8 meter
width of rectangle is 5 meter ............Answer
