First, u do -9+8x-4+8
Then, U simplify. The answer is 8x-5
The first digit can be any one of the numbers 2-9 That a total of 8 numbers.
The next 6 digits can be any permutation of 6 from the numbers 0 to 9.
(10 numbers)
nPr = n! / r!
so here we have 10P6 = 10! / 6! = 10*9*8*7 = 5040
So final answer is 8 * 5040 = 40,320
The factored expression would look like this : 3(x+8)(x-8)
18000 x 6/100 (Because 6%)
1080 each year.
Hope I helped!
I believed there is a typo error in the choices. Below I assume that the correct choices:
<span>A. 9 (3+4)
</span>B. 9 (4+5)
C. 7(4+5)
D. 7(3+6)
The answer is letter A which is 9 (3+4) the greatest common denominator of 27 and 36 is 9. The factor of 27 is 9 and 3 while for 36 is 9 and 4. To check the answer you need to solve 9 (3+4) which is 63 while 27 + 36 is also 63.
