Sodium oxide is a simple strongly basic oxide. It is basic because it contains the oxide ion, O2-, which is a very strong base with a high tendency to combine with hydrogen ions. Reaction with water: Sodium oxide reacts exothermically with cold water to produce sodium hydroxide solution
Answer:
A.
Step-by-step explanation:
Factoring is the process of taking common terms out of an expression such that one can represent the expression as the result of smaller values. When given the following expression:
First, represent the linear term as the sum of two terms such that each term shares a common factor with the other terms in the expression.
Now take out the common factors,
Thus, the correct option is choice (A).
Step-by-step explanation:
you could not find the formula ?
the volume of a cylinder is ground area × height.
and the ground area is a circle.
so, in total, we have
pi×r²×h
r being the radius (half the diameter), h being the height.
therefore, the volume of the given cylinder is
pi×(6/2)²×7 = pi×3²×7 = pi×63 = 197.9203372... mm³
5p+2=4p-1
1p+2=-1
1p=-3
p=-3
