Use the proportion to find the missing dimension of the original rectangle. 1. Set up the proportion: StartFraction x over three-fifths EndFraction = StartFraction 20 over 12 EndFraction 2. Use cross products: 12(x) = 20(3 5 ) 3. Simplify: 12x = 4. Divide:

2nd one in the first row is correct

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.
