Answer:

36

Step-by-step explanation:

7x+4 = 15x-12

7x = 15x-16

-8x = -16

-8x/-8 = -16/-8

x = 2

BD = 15x-12 + 9x

BD = 15(2)-12 + 9(2)

BD = 30-12 + 18

BD = 18 + 18

BD = 38

ANTONII [103]

Answer:

Step-by-step explanation:

Recursive formula

tn = t_n-1 / 4

t2 = t1 / 4

t2 = 10240

t1 = 10240 / 4 = 2560

Explicit formula

tn = 10240 / 4^(n-1)

t4 = 10240 / 4^(4 - 1)

t4 = 10240 / 4^3

t4 = 10240 / 64

t4 = 160

t8 = 10240 / 4^7

t8 = 0,625
