Hey the question is, " the length of a rectangle is twice its width. the perimeter of the rectangle is 126 feet."

42 = l

21 = w

Step-by-step explanation:

{l = 2w

{126 = 2w + 2l

126 = 2w + 2[2w]

126 = 2w + 4w

126 = 6w

21 = w [Plug this back into both equations to get the length of 42]; 42 = l

I am joyous to assist you anytime.

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
