Write an equivalent expression in standard form for (x−4)(2x2−3x+9) .What is the coefficient of the "x" term of the new expression?

A) -11
B) -3
C) 2
D) 21
E) 36

its 21

Step-by-step explanation:

21 21 21 21 21

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.
