The equations that can be used to determine the length of the room are:
y(y + 5) = 750
y²– 5y = 750
(y - 30) (y + 25) = 0
<h3>What are the equations that can be used to determine the length of the room?</h3>
A rectangle is a two-dimensional object that has four sides and four right angles. The sides of a rectangle are known as the width and the length. A rectangle has two diagonals of equal length which bisect each other at right angles.
Area of a rectangle = length x width
750 = y x (y - 5)
750 = y² - 5y
y² - 5y - 750 = 0
The factors of -750y² that add up to -5y are 25y and -30
(y² + 25y)(-30y - 750) = 0
y(y + 25) = 0
-30(y + 25) = 0
(y - 30) (y + 25) = 0
Here is the complete question:
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? Select three options. y(y + 5) = 750 y2 – 5y = 750 750 – y(y – 5) = 0 y(y – 5) + 750 = 0 (y + 25)(y – 30) = 0

Answer:
44 is the answer for the question
Step-by-step explanation:
x=2/10 - 3/5
Divide
x + 1/5=3/5
Subtract 1/5 from both sides of the equation
x + 1/5 - 1/5= 3/5 - 1/5
x=2/5
