Ella simplifies (3b+4r)+(-2b-r) and says the result is b+5r. what error did ella make? a. ella incorrectly combined the b coefficients. the correctly simplified expression is 5b+5r. b. ella incorrectly combined the b coefficients. the correctly simplified expression is -b+5r. c. ella incorrectly combined the r coefficients. the correctly simplified expression is b-5r. d. ella incorrectly combined the r coefficients. the correctly simplified expression is b+3r.

b. the decimal could be two-tenths.

step-by-step explanation:

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.
