Which are steps that could be used to solve 0 = 9(x2 + 6x) – 18 by completing the square? check all that apply. 18 + 81 = 9(x2 + 6x + 9) 18 + 9 = 9(x2 + 6x + 9) 18 + 36 = 9(x2 + 6x + 36) 11 = (x + 3)2 square root 342 = (x + 6)2 square root 99 = (x + 3)2

18 + 81 = 9(x2 + 6x + 9) and 11 = (x + 3)2

Step-by-step explanation

I took it on test

A and D      

18 + 81 = 9(x2 + 6x + 9)

and

11 = (x + 3)2

its 69.420

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
