If there is an increase in the money supply that causes money to lose its purchasing power and leads to inflation

Which region represents the solution to the given system of inequalities? |-0.5x+y23 | 1.5x+ys-1 5 4 -3 -2 -1 1 2 3 4

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?
