All we need is to put this form in the vertex form f(x) = (ax+b)^2 + c
So we have <span>f (x)= 3x^2+12x+11 ....
Let's complete the square (if you aware of it)
</span><span>
f(x)= 3x^2+12x+11 = 3(x^2+4x)+11 = 3(x^2+4x+4-4)+11
=</span><span> 3([x^2+4x+4]-4)+11 = 3[(x+2)^2-4]+11 =3</span><span>(x+2)^2 - 12 +11 = 3</span><span><span>(x+2)^2 -1
so our form would be:

Here is a parabola with vertex of (-2,-1) and with positive </span> slope (concave up)
</span>
I hope that

Answer:
If the rest of the question is:
Each game is a win or a loss.
He wins three fifths of his first 40 games.
He then wins his next 12 games.
For all 52 games, work out the ratio wins : losses
Give your answer in its simplest form.
then the answer is below ↓
Step-by-step explanation:
9:4
of his first 40 games: 3/5 *40=3*8=24 wins
=> of his first 40 games: 24 wins and 40-24=16 losses
next 12 games: 12 wins
so, for all 52 games: 24+12=36 wins and 16 losses
36 wins and 16 losses
wins: losses=> 36:16=> 9:4
Answer:
3 cans of white paint
Step-by-step explanation:
.25white xwhite
_______=_______
.50blue 6blue
cross multiply .50x =1.5
divide by .50
and x = 3
2/3 = 8/12
5/6 = 10/12
10/12, 8/12, 5/12
5/6, 2/3, 5/12 is the order
