It’s A. The first option. Also pls brainlist
Answer:
D. 9990 possible combinations
Step-by-step explanation:
The first digit has 10 choices (can be all of them), the second digit also has 10 choices. The third and fourth digits also have 10 choices.
Multiply them together you get 10*10*10*10 = 10000 possible combinations.
But since all 4 characters cannot be the same, we subtract 10 from 10000 (there are 10 combinations which the 4 characters are the same: 1111, 2222, 3333, 4444, 5555, 6666, 7777, 8888, 9999, and 0000) and we get 9990.
Imagine he second side is x so the first side is (x-3) and the third side is (x+4)
So x + (x-3) + (x+4) = 34
3x+1 = 34
3x=33
X=11
So longest side is (x+4) so 11+4=15
15m
Let, the numbers are: x, (x+1), (x+2)
Now, x+x+1+x+2= 11
3x + 3 = 54
3x = 51
x = 51/3
x = 17
So, largest number would be: (x+2) = (17+2) = 19
In short, Your Final answer would be 19
Hope this helps!
