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
