Iam trying to get this answer this related 7th grade advance math

Well, I believe the question is asking for Circumference - C. As the question is asking for the amount of ft of monkey grass needed to go Around the circular flower bed.

To solve for Circumference, first solve for the radius variable in the equation.

A = 36 Pi
A = r ^ 2 Pi

R ^2 = 36
R = square root of 36 = 6.

C = 2 Pi R
C = 2 Pi (6)
C = 12 Pi feet.

I believe the correct answer is B. 12 Pi feet.

You will have to read to get the 4 main points and the axis of symmetry.

Step-by-step explanation:

Let's get the roots out of the way first. The first thing to try is just factoring it.

The x^2 factors have opposite signs so you get

(x        )(-x     )

The next problem is to deal with the 3. It has only numbers making it up: itself and 1. So we can pud the 3 somewhere, but where.  But we know that the signs on the three must be the same +1 and + 3 or - 1 and - 3. It is a pure guess. on which will work

(x  3)(-x + 1) The minus and plus are just place holders. And finally the 2.

(x + 3)(-2x + 1). Now the only way you can check this is to foil it.

-2x^2 - 6x + x + 3

-2x^2 - 5x + 3

We have the factors. This was just guess work.

Roots

x+3 = 0

x = - 3  is one root.

-2x + 1 = 0

- 2x = -1

x = 1/2

Answer for roots (1/2,0)(-3,0)

============================

Now we go for the vertex.

1. take out - 2 only for the first 2 terms.

y = -2(x^2 + (5/2)x ... ) + 3 The three goes outside the brackets.

2. Take the coefficient inf front of the x. 1/2 it and square the results. Add that inside the brackets

y = -2(x^2 + (5/2)x + (5/4)^2 ) + 3

3. Whatever you do inside the brackets, you have to made an adjustment for after the 3. You also have to take the - 2 into account. These last 2 later.

(5/4)^2    square 5/4(25/16)    This goes inside the bracketsy = -2[x^2 + (5/2)x + (25/16)] + 3

4. What goes after the 3?

-2(25/16) = - 25/8 This is what essentially goes after the three. But should it be minus?The answer is no. That was something the - 2 brought in with it. Since the - 2 makes 25/8 minus, we should be putting +25/8 after the three. That will mean we have added nothing to the equation.y = - 2 (x^2 + (5/2)x + 25/16) )+ 3 + 25/8  Combiney = - 2 (x^2 + (5/2)x + 25/16) ) + 6.125

5. Write the vertex form of the equation.

y = -2(x + 5/4)^2 + 6.126

The vertex = (-5/4, 6.125

====================

The axis of symmetry is

x + 5/4 = 0

x = - 5/4

Y intercept

x = 0

y = -2(0)^2 - 5(0) + 3

y intercept = (0,3)

Graph

Red line with the 4 major points is y = -2x^2 - 5x + 3

Blue line is the axis of symmetry x = -5/4
