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

y = 3(x² + 3x -6)

Step-by-step explanation:

We have to rewrite the equation y = 3x² + 9x - 18 in the form of y = a(x - h)² + k.

So first step will be

y = 3(x² + 3x - 6)

y = 3(x² + 3x + 9/4 -9/4 -6) = 3(x² + 3x + 9/4 - 33/4)

y = 3(x + 3/2)² - 99/4

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
