4(2x - 1) + 2x + 2 = 28

x=3

Step-by-step explanation:

isolate the variable by dividing each side by factors that dont contain the variable

Step-by-step explanation:

8x-4+2x+2=28

10x-2=28

10x=28+2

10x=30

x=3

it is b)

hope this : )

step-by-step explanation:

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
