Answer:
24
Step-by-step explanation:
Let 12x represent the original number.
One fourth of that number can be represented by 3x, and one third of the number can be represented by 4x.
Create an equation that sets this equal to 38, and solve for x:
12x + 3x + 4x = 38
19x = 38
x = 2
The original number is represented by 12x, so plug in 2 as x:
12(2)
= 24
So, the original number is 24.

The simplified expression of (x + y)(x - y) is x^2 - y^2
<h3>How to solve the expression?</h3>
The expression is given as:
(x + y)(x - y)
Expand the bracket
x(x - y) + y(x -y)
Further, expand
x^2 - xy + xy - y^2
Evaluate the like terms
x^2 - y^2
Hence, the simplified expression of (x + y)(x - y) is x^2 - y^2
