If you wrote the expression correctly, then
Is a polynomial, and thus defined everywhere: its domain is the set of all real numbers.
If, by chance, you meant
Then we must exclude the point x=4 from the domain, since that value would cause the denominator to vanish. So, the domain would be the set of real numbers, minus the number 4.

Answer:
34
Step-by-step explanation:
Answer:
8,9
Step-by-step explanation:
(x)^2+(x+1)^2=145
x²+x²+2x+1=145
2x²+2x+1-145=0
x²+x-72=0
x²+9x-8x-72=0
x(x+9)-8(x+9)=0
(x+9)(x-8)=0
x=-9(rejected being negative)
x=8
x+1=8+1=9
