Answer:
if x=-1 then its is NOT in the domain of h.
Step-by-step explanation:
Domain is the set of values for which the function is defined.
we are given the function
h(x) = x + 1 / x^2 + 2x + 1
h(x) = x+1 /x^2+x+x+1
h(x) = x+1/x(x+1)+1(x+1)
h(x) = x+1/(x+1)(x+1)
h(x) = x+1/(x+1)^2
So, the function h(x) is defined when x ≠ -1
Its is not defined when x=-1
So, if x=-1 then its is NOT in the domain of h.
1. Factor the expression 

2. Since
is placed in the denominator of the given expression, then 
3. Now the expression can be simplified:

Answer:
Answer your own question.
Step-by-step explanation:
Listen to your teacher.
It is 20.
1st: set up a proportion. --> 95/100=19/x
2nd: cross multiply. --> 95 times x=95x. 100 times 19=1900.
3rd: divide 1900 by 95. --> 1900÷95=20
There you go! Your answer is 20
