First lets write this out:-
?
19 - 10 = 20 - 10
Now lets solve:-
19 - 10 =9
?
9 = 20 - 10
20 - 10 = 10
9 ≠ 10
Since 9 does not equal 10:-
19 - 10 ≠ 20 - 10

Answer:

Step-by-step explanation:
(f g)(x) is equal to f(x) times g(x). So you just need to multiply both of the equations together. Use the foil method to multiply (x+2)(x-4)

I have attached an image to better explain the foil method
Answer:
Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate platform independence.
Step-by-step explanation:
Hierarchical layers of abstraction in computers:
Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate platform independence.
In Hierarchical layers, users work independently at each level of the hierarchy.
example:
Abstraction in computing is language abstraction
Development of programming languages from machine language to assembly language and then high-level language is an example of Hierarchical layers of abstraction. Here each stage is a base for the next stage.
