Answer:
x=1
Step-by-step explanation:
We have,
h(x) = 5-2x
h(x)=3
Now, 
h(x)=5-2x=3
or,5-2x=3
or,5-3=2x
or,2/2=x
Therefore, x=1 when h(x)=3
 
        
                    
             
        
        
        
10 1/2 ft=2x-18 in
convert ft to in--10 1/2ft=126 in
126=2x-18
2x=144
x=<em>72 inches or 6 feet</em>

 is also true" holds, you can form the truth table:

When the result of the column  takes value 1 (true), the result of the column
 takes value 1 (true), the result of the column   is not always 1, then the statement is false.
 is not always 1, then the statement is false.
