Answer:
a square backyard with width (x - 9)
Step-by-step explanation:
x²−18x + 81 = x² - (2 x 9) x + 9² = (x - 9)²
width = area / length = (x - 9)² / (x - 9) = x - 9
Length = width
This is a square backyard

Answer: Vertex = (2, -15)  2nd point = (0, -3)
<u>Step-by-step explanation:</u>
g(x) = 3x² - 12x - 3
       = 3(x² - 4x - 1)
           a=1   b=-4  c=-1
Find the x-value of the vertex by using the formula for the axis of symmetry: 

       
          = 2
Find the y-value of the vertex by plugging the x-value (above) into the given equation: g(x) = 3x² - 12x - 3
g(2) = 3(2)² - 12(2) - 3
        = 12  - 24 - 3
        = -15
So, the vertex is (2, -15)  ←  PLOT THIS COORDINATE
Now, choose a different x-value.  Plug it into the equation and solve for y. <em>I chose x = 0</em>
g(0) = 3(0)² - 12(0) - 3
        = 0  - 0 - 3
        = -3
So, an additional point is (0, -3)  ←  PLOT THIS COORDINATE
 
        
             
        
        
        
Answer:
C  - 22
Step-by-step explanation:
Put in '3 ' for 'x' in both of the equations....then multiply the results together
f(3)  = 3 (3)^2 - 5 = 22
g(3) =  -1 
22 * -1  = -22
