Answer:
The possible midpoints are (5.5,8) and (5.5,3)
Step-by-step explanation:
Given
Required
Determine the midpoint of DE
First, we need to determine the coordinates of E
If E is to the right of DE;
Hence, the coordinate is (11,16)
Else:
Hence, the coordinate is (11,6)
<em>The possible midpoints are (5.5,8) and (5.5,3)</em>
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
