Answer:
<h2>Make the points more Appealing</h2>
Step-by-step explanation:
B. The expression has 4 factors and 0 constants.
The factors separately are:
4
a
b
(c+3)
Factors are numbers or expressions that produce a givens product.
Looking at the expression we can rewrite it as:
4 x a x b x (c+3)
The overall value with be the product of all the factors.

Answer:
(a) If r is any rational number and s is any irrational number, then r/s is rational
(b) The statement is false when r is 0
Step-by-step explanation:
Given
rational number
irrational number
irrational number
Solving (a): The negation
To get the negation of a statement, we only need to negate the end result
In other words, the number type of r and s will remain the same, but r/s will be negated.
So, the negation is:
rational number
irrational number
rational number
Solving (b): When r/s is irrational is false
Given that:
irrational number
Set r to 0
So:

-- rational
<em>Hence, the statement is false when r is 0</em>
Order of the people does not affect the total number of ways. Thus, we use combinations.
Total combinations: 20C5 = 15,504 ways.
