0.4 is four tenths. 0.4 = 4/10=2/5
Answer:
x = 5
Step-by-step explanation:
The difference between consecutive terms will be equal , then
a₂ - a₁ = a₃ - a₂ , that is
x + 9 - (3x - 2) = 2x + 5 - (x + 9) ← distribute parenthesis on both sides
x + 9 - 3x + 2 = 2x + 5 - x - 9 , simplify both sides
- 2x + 11 = x - 4 ( subtract x from both sides )
- 3x + 11 = - 4 ( subtract 11 from both sides )
- 3x = - 15 ( divide both sides by - 3 )
x = 5
Answer: A
Step-by-step explanation:
The cube with 1 face with area 36 ft^2 has an edge of 6 ft.
The other cube has edges 2 * 6 = 12 ft long and its volume is 12^3
= 1728 ft^3 (answer).
For 
to be conservative, we need to have
Integrate the first PDE with respect to 
:
Differentiate with respect to 
:
Now differentiate 
with respect to 
:
So we have
so is indeed conservative.
