Answer:
Option 3)
8(a + 7) can be rewritten as 8(a) + 8(7).
Option 7)
An equivalent expression is 8a + 56
Step-by-step explanation:
We are given the following expression:
We can simplify the expression by distributing 8 over (a+7).
Distributive property:
Simplifying the expression, we get,

Answer:
Following are the solution to the given points:
Step-by-step explanation:
In point 1:
The Reflexive closure:
Relationship R reflexive closure becomes achieved with both the addition(a,a) to R Therefore, (a,a) is
Thus, the reflexive closure:
In point 2:
The Symmetric closure:
R relation symmetrically closes by adding(b,a) to R for each (a,b) of R Therefore, here (b,a) is:
Thus, the Symmetrical closure:
