<span>42=-2d+6
Here, to find d, you need to separate it on one side.
First, subtract 6 from both sides.
42-6 = -2d + 6 - 6
36 = -2d
Now divide both sides by -2.
36/-2 = -2/-2d
-18 = d
The answer to this problem is -18, or d = -18.</span>
        
                    
             
        
        
        
The graph of a quadratic function is a parabola. The axis of symmetry<span> of a parabola is a vertical line that divides the parabola into two congruent halves. The </span>axis of symmetry<span>always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the </span>axis of symmetry<span> of the parabola.</span>
        
             
        
        
        
Answer:
Option B
Step-by-step explanation:
Length of the rectangular sand box is given by the function,
F(x) = 3x³ + 6x - 2
Width of the sand box is represented by the function,
W(x) = 2x² - 4
Area function for the sand box will be,
Area of a rectangle = Length × Width
F(x) × W(x) = (3x³ + 6x - 2)(2x² - 4)
                  = 2x²(3x³ + 6x - 2) - 4(3x³ + 6x - 2)
                  = 6x⁵+ 12x³ - 4x²- 12x³- 24x + 8
                  = 6x⁵- 4x²- 24x + 8
Therefore, Area function will be represented by a polynomial degree of 5.
Option B will be the answer.
