Answer:
There is a few ways to answer this:
The actual and simple way: 19
The way we use for fun, (meme way): 910
P = 2L + 2W
P = 2(6x - 2) + 2(x - 1)
P = 12x - 4 + 2x - 2
P = 14x - 6
A <<<< Answer
Answer:
The length of the altitude from the right angle to the hypotenuse of a right triangle is the <u>geometric</u> mean of the two segments that make the hypotenuse.
Each digit can be 0-9 ( 10 numbers)
there are 9 numbers in a social security number
multiply 10 nine times:
10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 1,000,000,000 ( 1 billion) possibilities.
the restriction is it can't be all zeros so subtract 1 from the total
1,000,000,000 - 1 = 999,999,999 combinations
