Ответ:
2W²-W-28 = 0 is the equation.
Step-by-step explanation:
To form the equation we should always follow the statement as said.
First statement is
The length (L) of a rectangle is 1 less than twice of width (W).
Means L = 2W - 1 (1)
Second statement
Area of the rectangle is 28 feet²
Means L×W = 28 (2)
Now by putting the value of L from equation 1 to equation 2.
(2W - 1)×W = 28
2W² - W = 28
2W² - W - 28 = 0
This the equation that represents the situation.
