5(x^2+8x)=14
5(x^2+8x+16)=5(x^2+8x)+5*16=5(x^2+8x)+80=14+80=94
The correct choice is the second one
For Chris, the calculation for his monthly telephone expense is as follows:
Where "x" denotes each minute used.
Given that Chris can afford a bill of $86, we have:
The total minutes of usage must not exceed 500 per month. Consequently, the viable choice is option C.
Answer:
Option C
Response:
1. Closure
2. Distributive
3. Closure
Detailed explanation:
In this scenario, we are examining the properties that each equation demonstrates.
The first equation shows the closure property.
This indicates that whether we add in one direction or the other, the result remains unchanged. Therefore, we conclude that addition conforms to the closure property in this case.
The third equation also shows the closure property. Regardless of how we approach the addition for this equation, the outcome remains consistent.
The second equation displays the distributive property.
Each element within the parentheses is multiplied by the negative sign before we proceed with further calculations.
