Final answer:
None of the given options correctly describe the truth about Z^2 when Z^2=26, as they involve concepts not applicable to algebraic expressions or present incorrect statements. Therefore, none of the options provided is a correct description of the truth about Z^2 when Z^2=26.
Step-by-step explanation:
When given that Z^2=26, you are asked which statement must be true regarding Z^2. Let's examine the options provided:
- (a) Z^2 is complementary to 25. The term "complementary" is generally used in the context of angles, and it means that two angles add up to 90 degrees. This is not relevant to the question as Z^2 is an expression of algebra, not geometry.
- (b) m2=m^28 is not relevant to our problem and seems to be a typographical error.
- (c) Z^2 is supplementary to 28. Like "complementary", "supplementary" refers to angles, implying that two angles add up to 180 degrees. Again, this is not applicable here.
- (d) Z^2=25. This statement is clearly incorrect as we are given Z^2=26.
Therefore, none of the options provided is a correct description of the truth about Z^2 when Z^2=26.
