Can someone please help me with #9

see below

Step-by-step explanation:  5 19 3  52

BIG square area minus little square area equals the shaded area

big area - little area = shaded area

S²  -  s²  =  shaded area

8.5² - 6² =  shaded area

72.25 - 36 =    units²

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.
