Answer:
Step-by-step explanation:
Sum a with a-s ;b with b-s so:
0.75a + 10b + a – 2b=0.75a+a+10b-2b=1.75a+8b
Percent increase = ((new number - original number) / (original number)) x 100.
percent increase = ((3000 - 2500) / 2500)) x 100 =
(500 / 2500)....x 100 =
0.2 x 100 =
20% increase <====
The number of terms in the binomial expansion of (3x-5)^9 is 10
The list is long, but here goes:
10/12, 15/18, 20/24, 25/30, 30/36, ... and so on.
