Answer:
below
Step-by-step explanation:
Geometric series with first term 3 and common ratio r.
Last variety = 3 * 2^(12-1) = 6144.
Total = 3 * (2^12 - 1) / (2-1)
= 12285
P1. C
P2. A
3.D i think
4. C and D maybe
Answer: (2 - 8x2 - 15) = -29/1 = -29
(2 + 12x - 3x) = 0
(2 + 12•x - 3•x) = 0
9x = -2
x = -2/
9
≈ -0.222222
