The area of a rectangular room is 750 square feet. the width of the room is 5 feet less than the length of the room.

which equations can be used to solve for y, the length of the room? check all that apply.

y(y + 5) = 750
y2 – 5y = 750
750 – y(y – 5) = 0
y(y – 5) + 750 = 0
(y + 25)(y – 30) = 0

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

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
