I'm assuming there is a + sign between the 5h & the 2.
But you first get:
15h^2-15h+6h-6
Which simplifies to:
15h^2-9h-6
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.

First multiply both 4 and 18:
4*18=72
According to formula:
G(a1.a2) = sqrt(a1.a2)
G(a1.a2.a3) = 1/3 root of (a1.a2.a3)
As there are only 2 numbers whose geometric mean to be calculated, we take square root of multiplication of two numbers.
Sqrt(72) = 8.4852
