- x = 9
Step-by-step explanation:
A) A number cannot be less than itself, but can be equal to itself.
In each case, the left side of the inequality evaluates to 19:
4(5) -1 = 20 -1 = 19
It is true that 19 is less than or equal to 19. This is true because 19 = 19.
It is not true that 19 is less than 19. A number cannot be less than itself.

Answer:
4 cm
Step-by-step explanation:
The Area of a parallelogram is given by :

Area = base * height
120 = base * 30
Base = 120 / 30
Base of parallelogram = 4 cm
