Answer:
The correct answer is 4294967296 possible ways to complete such a test.
Step-by-step explanation:
Step 1
The first step is to define the fundamental principle of counting. The fundamental principle of counting states that if a process can be carried out in n steps, where there are 
ways to complete the first step, 
ways to complete the second step, 
, and 
ways to complete the 
step, this process can be carried out in 
ways.
Step 2
We use the fundamental principle of counting with 
for a total of 
steps. This test can be carried out in 
ways. This comes from multiplying 4 by itself 16 times.
Answer:
R = rows
C = columns
The chairs will be arranged in a way such that R * C 
70
We know that R 
20
70 / 20 = 3.5; however, you can't have half of a chair.
So find all the factors of 70 which don't exceed 20.
1, 70
2, 35

5, 14</h2><h2>
7, 10</h2><h2>
</h2><h2>There are four ways that Brooke can set up the chairs:</h2><h2>5 rows of 14</h2><h2>7 rows of 10</h2><h2>10 rows of 7</h2><h2>14 rows of 5</h2>
A ratio is a one or more letter term
3x+12=39
Minors 12 on both side
3x=27
Divide 3 on both side
X=9
(5x^2-15x) (-2x+6)
5x (x-3) -2 (x-3)
(5x-2) (x-3)
