We use equations for geometric sequence. We do as follows:<span>
a(n) = a(1) r^(n-1)
20 = ar^(2-1)
</span>20 = ar<span>
a = 20/r
11.25= ar^(4-1)
</span>11.25 = ar^3
<span>11.25 = (20/r)r^3
r = 0.75
Hope this answers the question. Have a nice day.</span>
Answer:
12x+4
Step-by-step explanation:
Cross multiply denominators by numerators so:
8(x)+ 4(x+1)
8x+4x+4
Collect like terms to get 12x+4
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
