A computer monitor has a rectangular viewing area of 135 square inches. The viewing area is 9 inches tall. What is the
width of the viewing area?

15 inches wide

Step-by-step explanation:

to find the area of a rectangle you would multiply the height by the width so this would be the opposite because we have the area which is 135 in.² so we would divide 135 by 9 which would give us 15.

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
