What is the first step when rewriting y = 3x2 + 9x – 18 in the form y = a(x – h)2 + k? 3 must be factored from 3x2 + 9x x must be factored from 3x2 + 9x 9 must be factored from 9x – 18 3 must be factored from 3x2 – 18

3 must be factored out from

Step-by-step explanation:

3 must be factored out from leading to

and now the remaining trinomial is very simple to factor out with binomials of the form

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

he kicked it up? is this the answer ?

step-by-step explanation:
