Answer:
None.
Step-by-step explanation:
The only possible restriction in the rational expression 
can originate in its denominator being zero for some values of a. However, since the denominator in this case (a^2+4) is always positive (and larger or equal to 4) for all values, no restrictions on the variable a exist.
A number where the digit 3 has a value ten times greater than the 3 in 145,317 can be 143,417.

How to work with place values?</h3>
In any number, the place value refers to the "place" that a digit has on a number. The first one is the units place, the second is the tens place, and so on.
As more in the left is the place value, the largest value it represents.
Particularly, in 145,317
The 3 is on the third place, so it represents the value 300.
For example, in 143,417
The 3 is more in the left than before, this time on the fourth place, this time the value of the 3 is 3,000.
Then, a number where the digit 3 has a value ten times greater than the 3 in 145,317 can be 143,417.

Sorry no answer just wanted to say your pfp is hot
Use a variable to represent the number of hours the technician will work, plus the $50.
50+25x
This would be the expression used to find the amount of money the technician needs.
