4, 56, 18B, 34, 10, 20, 26, 38 I need help with. Thanks

4. , we have

has no solutions.
YES IT DOES WHEN YOU CONSIDER IMAGINARY NUMBERS AND WE ARE DOING THAT IN THIS SECTION!

If we consider imaginary numbers:
36x2 = -49

B. As has no solutions, has no x-intercepts.

6.  

16.  

56. .
(units)
WELL, WHAT ARE THE UNITS THEN? 
Based on the above information, there is inadequate evidence to conclude the unit of the answer. (Unless you tell me what the original word problem is)

18. , so 7x-1=0

x=1/7.

B. is x=1/7. So, x-intercept is 1/7. PLEASE PROVIDE THIS AS A POINT
