5x + 2 is a denominator.
A denominator cannot equal zero since division by zero is undefined.
Set the denominator equal to zero and solve for x to find which value of x makes the denominator zero.
5x + 2 = 0
5x = -2
x = -2/5
The non-permissible replacement for the variable is -2/5.

Answer: 51,53,55,57
Discussion. By the triangle inequality the sum of the lengths of any two sides is greater than or equal to the third side. In our case, 3 + 54 = 57, so the third side must be less than or equal to 57.

It’s y=x+5 your welcome have a nice day
Having a positive exponent means
having a positive number as a power for a value or a variable.For example:
Here, the variable
x has a positive exponent because it has a power of positive (+) 2
This expression has a positive exponent because the number
1 has a power of positive (+)1 and the number
2 has a power of positive (+)4

This is not a positive exponent because the variable
x has a power of negative (-)2
The positive exponent for

is

.

This expression doesn't have a positive exponent. Though number
1 in the numerator has a positive power (exponent), the number
2 in the denominator has a power of negative (-)4
The positive exponent for

would be

.
NOTE: The terms Power and Exponent have he same meanine i.e. They are the same !!!
