What is the common ratio for this geometric sequence? 5,15,45,

3

Step-by-step explanation:

To find the common ration, we take the 2nd term and divide it by the first term

15/5  = 3

Let check by taking the third term and dividing by the 2nd term

45/15 =3

The common ratio is 3

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
