To accurately answer your question, I would need to know the specific statement you are referring to. Please provide the statement, and I will identify the property that justifies it.
Reflexive property
The property that justifies the statement is the transitive property of inequality. This property states that if one quantity is greater than another, and that second quantity is greater than a third, then the first quantity is also greater than the third. In this case, if (3x + 4 > 35) and (35 > 39), then it follows that (3x + 4 > 39). However, please note that the inequality as written seems incorrect; it should be (3x + 4 > 35) leading to (3x > 31) and not (39).
Reflexive
transitive
substitution property of equality
It is the property that equals plus equals are equals.
Substitution property.
2x(3x-1) = 6x2-2x because of the distributive property.
There is no property that justifies it. The equation is true for some values of x, not for others.
