Answer:
Option B , C and E are correct
(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 =
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+25)(y-30)=0
Therefore, the equation which can be used to solve for y are;
, and (y+25)(y-30)=0
Step-by-step explanation:
