Step-by-step explanation:
Cassidy’s family is driving home from vacation at an average speed of 55 mph.
Initially, at x = 0 hours, the family is y = 0 miles away form home. We get the first point (0,0).
After x = 2 hours, the family is y = 110 miles from home. We get the second point (2,110).
The equation in point-slope form that represents their distance y from home, after x hours is
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
