Answer: a = 36 and b = 9
Explanation:
(6x-3)(6x+3)
= 36x² - 18x - 18x - 9
= 36x² - 9
(6x-3)(6x+3) = ax² - b
36x² - 9 = ax² - b
a = 36 and b = 9

Answer:
7,366,327.50 pascals
Step-by-step explanation:
we know that
1 atm= 101,325 pascals
we have
72.7 am
Convert to pascals
72.7 atm=72.7*101,325=7,366,327.50 pascals
Let,
the no. of adults be "x"
then, the no. of childern = total people - total adults
= (30 - x)
Now,
According to the quesiton,
2 (30 - x) + 5x = 87
60 - 2x + 5x = 87
60 + 3x = 87
3x = 87 - 60
3x = 27
x = 27 / 3
x = 9
So, there were 9 adults in the group
