I keep getting 3.2 but I don’t think is right

x=14

Step-by-step explanation:

The interior angles of a regular decagon are the same and add up to 1440.

10(10x+4)=1440

Oh Hi There!

Here’s ur answer

x = 14

The interior angels of a regular decagon are the same and add up to 1440..

10 (10x + 4) = 1440

3x^3-x^2+6x-9

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.
