Answer: OPTION C.
Step-by-step explanation:
1. The domain of the function given in the problem are all those values for which the function that is in the denomiantor is different from zero, because the division by 0 is not allowed.
2. You can make the denominator equal to zero and solve it, as you can see below:
![x^{3}-2x^{2}+x=0\\x(x^{2}-2x+1)=0\\x(x-1)(x-1)=0\\x=0\\x=1](https://tex.z-dn.net/?f=x%5E%7B3%7D-2x%5E%7B2%7D%2Bx%3D0%5C%5Cx%28x%5E%7B2%7D-2x%2B1%29%3D0%5C%5Cx%28x-1%29%28x-1%29%3D0%5C%5Cx%3D0%5C%5Cx%3D1)
3. Therefore, the domain is:
(-∞,0)U(0,1)U(1,∞)
Answer:
Some.
Terms that include a number and a letter are expressions.
Set up the equation
x = the smaller number
x + 15 = the larger number
x + x + 15 =39
solve for x
this will be the smaller number
add 15 to get the larger number
