Final answer:
The missing reason in Rhett's algebraic proof is likely the Division Property of Equality, as this property is used when you multiply or divide both sides of an equation by the same number.
Step-by-step explanation:
Rhett was solving an algebraic proof and needed to identify what reason is missing from his proof. The choices provided were a) Given, b) Distributive Property, c) Addition or Subtraction Property of Equality, and d) Division Property of Equality. When working with proofs, understanding properties and operations that maintain equality is essential. If Rhett was required to multiply or divide both sides of an equation by the same number, he would use the Division Property of Equality. This is because multiplying or dividing both sides by the same number will not change the equality of the equation, provided that the operation applies to every term on either side of the equality. When an equation side has more than one term, you should enclose it in brackets before performing multiplication or division to ensure the operation affects each term equally.
