What are you even talking about... What is the ???
The exact number of dogs is between 22,500 - 23,499
Answer:
Option B , C and E are correct
![750 -y(y-5)=0](https://tex.z-dn.net/?f=750%20-y%28y-5%29%3D0)
(y+25)(y-30)=0
Step-by-step explanation:
Given : Area of rectangular room is 750 square feet.
Width of the room is 5 feet less than the length of the room.
Let y be the length of the room
then,
As per the given condition
width of the room is: y-5
Area of rectangle is multiply the length by its width.
Area of rectangle = ![length \times width](https://tex.z-dn.net/?f=length%20%5Ctimes%20width)
Substitute the given values in above formula we get;
......[1]
or we can write this as;
750 -y(y-5)=0
[1] ⇒
or
or
![y^2-5y-750=0](https://tex.z-dn.net/?f=y%5E2-5y-750%3D0)
![y^2-25y+30y-750=0](https://tex.z-dn.net/?f=y%5E2-25y%2B30y-750%3D0)
(y+25)(y-30)=0
Therefore, the equation which can be used to solve for y are;
,
and (y+25)(y-30)=0
