-5(x+8)-3x
simplified would be
-8x-40
26 total letters, 10 total digits
with repeated letters/numbers:
26 * 26 *26 * 10* 10*10 = 17,576,000 ways
without repeats:
26 *25*24 *10 *9*8 = 11,232,000 ways
500,000,000,000 in scientific notation:
First you count to 0 zeros behind the 5 which is 11 zeros.
the scientific notation of 500,000,000,000 is:
₁₁
