umm, wheres the question?
Step-by-step explanation:
Answer:
Step-by-step explanation:
Differentiating, you get ...
... x·dy +y·dx +dx +dy = 2x·dx +2y·dy
Collecting terms gives ...
... dy(x +1 -2y) = dx(2x -y -1)
... dy/dx = -(2x -y -1)/(2y -x -1)
He wants the scale factor to be 1.8
So 2.5×1.8=4.5 and 5×1.8=9
And the border would also be known as the perimeter and perimeter is side+side+side+side and so on
9+9+4.5+4.5=27
he will need 27ft of wood for the border.
x > 7 x < 10
7 o---------------------o 10
This is not an empty set. x contains all of the values between 7 and 10.
Not possible. even thought the angles( the lines inside the triangles) are opposite sides of each other, it doesn’t match up
