720 codes.
There are 10 digits possible for the first digit of the code.
Since there can be no repeated digits, you subtract 1 and find there are only 9 possible digits for the second digit in the code.
Finally, subtract 1 again to find there are only 8 possible digits for the last digit.
Multiply these together to find the number of combinations.
10 * 9 * 8
90 * 8
720
So, there are 720 combinations if digits cannot be repeated.

Answer:
280.6 square units
Step-by-step explanation:
The formula for the area of an n-gon with radius r is useful here:
A = (n/2)r²sin(360°/n)
For your hexagon (n=6) with radius r=6√3, the area is ...
A = (6/2)(6√3)²sin(360°/6) = 324sin(60°) = 162√3 ≈ 280.6 . . . square units
Answer:
The poster is 11 inches wide and 19 inches in height.
Step-by-step explanation:
We take the given equation: (x^2+2x-15) and we add in 14 as our x variable:
((14)^2+2(14)-15) the answer we get from that is 209. The area of the poster is 209 square inches. Then we find the width by taking (x-3) in this case x is 14 so the width of the poster is 11. In order to find the height we divide the height by the width and we get 19.
Therefore:
Height= 19 Inches
Width= 11 Inches
Total Area= 209 Square Inches
