A postulate is a statement in math that is so obvious that it does not need to be proven, that is basically what it means, in layman's terms
So we will be using dimensional analysis to solve it as such:

In short, 23,843 kL is 6,291,029.02 (6,291,029 rounded to the whole gallon) gallons.
Answer:
No solution
Step-by-step explanation:
There are no values of x that make the equation true; hence making it have no solution.
The answer is 21.
Explanation:
5x3=15
15+6=21
There is an isosceles triangle.
The triangle is like two right triangles put together.
To find out the height of the triangle, we remove the other right triangle and we use the other triangle to find the height using the Pythagorean theorem.
Phytagoras Theorem :
b² = c² - a²
x² = 8² - (6÷2)²
x² = 64 - 3²
x² = 64 - 9
x² = 55
x = √55
So, the value of x is √55 (B)
