Answer:
The equivalent to -(-5.25) = 5.25
Explanation:
Given
![-(-5.25)](https://img.qammunity.org/2021/formulas/mathematics/high-school/9lg2csbc7rrof6pyf172wgkhbgxdamuxfs.png)
We need to determine the equivalent to -(-5.25)
some of the sign rules are:
+(+) = +
−(−) = +
+(−) = -
−(+) = -
Thus,
![-(-5.25)](https://img.qammunity.org/2021/formulas/mathematics/high-school/9lg2csbc7rrof6pyf172wgkhbgxdamuxfs.png)
Applying the rule: -a(-a) = a
![=5.25](https://img.qammunity.org/2021/formulas/mathematics/high-school/p5gjjeg6llnie5m2o5d1tuslksi1ofi66d.png)
Therefore, the equivalent to -(-5.25) = 5.25
