Can somone answer this ty!!

6

Step-by-step explanation:

you see that 4*30 gets us to 120 so you do 180 divided by 30 and you get 6

6 lbs of fertilizer

Step-by-step explanation:

Since 4 lbs of fertilizer can be used for 120 sq ft of soil, we can calculate how many sq ft 1 lbs of fertilizer can cover

1 lbs of fertilizer = 120/4 = 30 sq ft of soil

From this, we can find how many lbs of fertilizer is needed for 180 sq ft of soil

180/30 = 6 lbs of fertilizer

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
