Which equation represents y = x2 + 12x + 27 in vertex form? y = (x + 6)2 − 9

y = (x + 6)2 + 21

y = (x + 6)2 + 9

y = (x + 6)2 + 27

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
