The equations y=55x+50 and y=65x represents Rick's and Betty's trip.
Step-by-step explanation:
Given,
Head start of Rick = 50 miles
Speed of Rick = 55 mph
Let,
x be the number of hours
y be the total miles
Distance covered by Rick in x hours = Speed * Time + Head start
y = 55x + 50
Speed of Betty = 65 mph
Total miles = Speed*Time
y=65x
The equations y=55x+50 and y=65x represents Rick's and Betty's trip.

Answer: 3x^3 - 3x^2 - 4x - 4
Explanation:
(x - 2)(3x^2 + 3x + 2)
= x(3x^2 + 3x + 2) - 2(3x^2 + 3x + 2)
= 3x^3 + 3x^2 + 2x - 6x^2 - 6x - 4
= 3x^3 - 3x^2 - 4x - 4
