Answer:
10 rows with 6 passengers per row
Step-by-step explanation:
Let x be the number of rows and y the number of passengers per row.
Then we can interpret the story as the following two equations:
xy=60
(x+2)(y-1)=60
Solving these two equations:
y=60/x
(x+2)(60/x-1)=60 (substitute y)
60 - x + 120/x - 2 = 60 (multiply by -x)
x² + 2x - 120 = 0 (factor)
(x-10)(x+12) = 0
x = 10
y = 60/10 = 6
and indeed 10 * 6 = 60 and also 12 * 5 = 60

The greatest common factor is 45
Answer:
FIRST FOUR (4) TERM = 6, 18, 54,162.
COMMON RATIO = 3
Step-by-step explanation:
In geometric expression.
Tn = the nth term
a = first term
r = common ratio.
Let's take the First term of the G.P as 6 and the third term as 54. Let's find the common ratio.
3rd term will be written as:
T3 = ar² = 54
Given the first term as 6.
T3 = 6r² = 54
6r² = 54
r² = 54 / 6
r² = 9
r= √9
r = 3
Therefore common ratio = 3.
Let's use this information to get the fourth term.
T4 = ar³
when a = 6
and r = 3.
T4 = 6 * 3³
T4 = 6 * 27
T4 = 162
