Step-by-step explanation:
There are 5 different positions of 666:
666////
/666///
//666//
///666/
////666
The forward dashes represent any number from 0 to 9.
Case 1: "666////"
Number of ways = 10⁴ = 10,000.
Case 2: The other positions.
Since the 1st forward dash cannot be 0 (leading digit),
Number of ways for each position = 9 * 10³ = 9,000
Number of ways for all 4 positions = 9,000 * 4 = 36,000.
Total evil numbers = 10,000 + 36,000 = 46,000.

Answer:
89m
Step-by-step explanation:
First, find the area of the rectangle (ignoring the missing triangle inside). The area of the rectangle is its base times its height, which is 8*13=104. 
Next, find the area of the triangle. The area of the triangle is its base times height, divided by two. 
The width of one side of the rectangle is 13, and the width of the side of the rectangle is 8 (4 + 4). Therefore, subtract 8 from 13 and the missing section in the side of the rectangle is 5. 5 is equal to the base of the triangle. 
The height of the triangle is given, which is 6. As stated before, the area of a triangle is its base times height divided by two, which is 5*6/2 in this case. The area of the triangle is equal to 15. 
Now, subtract the area of the triangle from the area of the rectangle. 104-15=89.
 
        
             
        
        
        
Sample Equation:  3x - 3 = 27
Multiple step:
3x    -  3  =    27
 <u>       + 3       +3</u>  Step1. Remove the -3 by adding 3 to both sides
3x            =   30
<u>÷3                ÷ 3</u>  Step2. Remove the multiplicand 3 by dividing both sides by 3
x              =  10
To check: substitute x by its value
3x - 3 = 27
3(10) - 3 = 27
30 - 3 = 27
27 = 27
