Answer:
x² - 3x - 70 = 0 models this situation.
Step-by-step explanation:
Area of a rectangle = 70 inches²
Let the length of the rectangle = x inch
Since Length of the rectangle is 3 inches longer than the width of the rectangle.
Then width of the rectangle = (x - 3) inches
Now area = Length × width
70 = x(x - 3)
x² - 3x = 70
x² - 3x - 70 = 0
Therefore, x² - 3x - 70 = 0 models this situation.
