3x^2 + 9x + 6 = 0
3x^2 + 3x + 6x + 6 = 0
3x(x + 1) + 6(x + 1) = 0
(3x + 6)(x + 1) = 0
3x + 6 = 0 and x + 1 = 0
3x = -6 and x = -1
x = -2 and x = -1
Step-by-step explanation:
multiply the 1 1/2 by 2 to get 3.
find the closest number that is divisible by 3
3*7 is 21.
We now have to multiply 7 by 2 since we did that to our mixed number to get a whole number.
There is still a 1 1/2 left over. Simply add 1 to 14.
12.8 is the answer to this problem
Answer:
0.05 = 0.5/10
or
0.05 * 10 / 10 = 0.5/10
Step-by-step explanation:
Answer:
Air pressure = 
Step-by-step explanation:
Relationship between air pressure and altitude can be modeled by,
P = 14.7e
Where P = Air pressure
and h = altitude above the sea level
Air pressure on Mount Everest having altitude = 29028 feet abve the sea level will be,
P = 
= 
= 4.603
≈ 4.6 
Therefore, air pressure on Mount Everest = 4.6
