What range would the tower need to have to be sure that Geoff’s lost phone would ring?

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
