20. The hypotenuse of a right triangle is 22m long. The length of one leg is 0m less than the other. Find the lengths of the legs.
26. A turbo-jet flies 50 mph faster than a super-prop plane. If a turbo-jet goes 2000 mi in 3 hr less time than it takes the super-prop to go 2800 mi, find the speed of each plane
Please see the attached file.
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.  
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
B. is x=1/7. So, x-intercept is 1/7. PLEASE PROVIDE THIS AS A POINT
The solution provides detailed explanations and answer for the small algebra problems. Quadratic equations and functions are examined.
