Answer: x=4
Step-by-step explanation:
We know that line segment AC= AB + BC
we also know that AB= 3x+8 and BC= 2x-5
by substituting these, we get AC= (3x+8)+(2x-5)
AC is given as being 23, so we know that
23= (3x+8)+(2x-5)
by combining like terms, we get that
5x+3=23
simplify this to get that x=4

Answer:
The statement 
is neither a tautology nor a contradiction.
Step-by-step explanation:
A tautology is a statement that is always true.
A contradiction is a statement that is always false.
We are going to use a truth table to determine whether the statement is a tautology, contradiction, or neither
A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.
The statement is compound by these simple statements:
and we are going to use these simple statements to build the truth table.
The last column contains true and false values. Therefore, the statement is neither a tautology nor a contradiction.
