Answer:
The Correct option is C. Addition Property of Equality.
For above Equation by Elimination we use
Addition Property of equality
Step-by-step explanation:
Given:
Addition Property of Equality :
The property that states that if you add the same number to both sides of an equation, the sides remain equal (i.e., the equation continues to be true.)
Here equation is given as
3x + 4y = 38
+ 5x - 4y = -30
-------------------------------------
8x = 8
------------------------------------
Here +4y and -4y gets cancelled or becomes 0 hence 8x = 8.
For above Equation by Elimination we use

V = lwh
divide both sides by l and w,
V/(lw) = lwh/(lw)
h = V/(lw)

Answer: E
Step-by-step explanation: In mathematics, a theorem is a statement that has been proven on the basis of previously established statements, such as other theorems, and generally accepted statements, such as axioms. A theorem is a logical consequence of the axioms. ... Many mathematical theorems are conditional statements.
