Jim wants to put a fence around his garden to keep out the animals. How many feet of fencing does he need to buy? Fencing can only be sold in whole number quantities. Do not include units in your answer.

30

Step-by-step explanation:

you add the sides together. so it is: 12+5+8+5=30ft

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
