Answer:
A. 20
Step-by-step explanation:
look at this step:
4 : 5 = X : 25
X = 4×25/5 = 100/5 = 20
To simply the expression,we should remember an ! in math represents every number (til 1) before that one multiplied or "the product of the integers from 1 to n"
So now that we have the definitions we can simplify by finding the values of each:
(9x8x7x6x5x4x3x2x1)-(4x3x2x1)(5x4x3x2x1)
After simplifying this will equal to 3600

Answer:
756
Step-by-step explanation:
The ratio of areas is the square of the scale factor.
First, we find the scale factor from the blue solid to the red solid.
scale factor = 6/4 = 3/2
The ratio of areas is the square of the scale factor:
ratio of areas = (3/2)^2 = 9/4
volume of red solid = volume of blue solid * ratio of areas
volume of red solid = 336 m^2 * 9/4 = 756 m^2
Answer: S = 756 m^2
