Answer:
The equation in standard form is:
x^2-40x-6000 = 0
Step-by-step explanation:
Let the length of the field be x yards.
Now the width of the field is 40 yards less than the length of the field.
Thus, the width of the field would be (x-40) yards
Now, to calculate the area of the field, we simply multiply the length of the field by the width of the field.
Hence;
Since the shape is rectangular, the area is the product of the length and that of the width
x(x-40) =6,000
x^2 -40x = 6,000
x^2-40x-6000 = 0
Answer:
45.413 cm³
Step-by-step explanation:
Because the volume of a orament is 57 cm³ . The volume of twenty-seven oraments is 1242 cm³ . The volume of a cube is 46656 cm³
⇒The empty space is :
46656-1242=45414 ( cm³)
So the empty space is 45414 cm³
Answer:
Option D. 
Step-by-step explanation:
using a graphing tool
Graph and determine the vertex in each case
we know that
If the equation has a maximum value at x=-2, then the x-coordinate of the vertex must be equal to -2 and the parabola open downward
case A) 
The vertex is the point 
case B) 
The vertex is the point 
case C) 
The vertex is the point 
case D)
The vertex is the point 
-------> is the answer
see the attached figure
Answer: the equation for SU is 2(lb+bh+hl)
Step-by-step explanation: L stands for length B stands for base. H stand for height multiply that by 2
Step-by-step explanation:
-8x+5x-9=6
-8x+5x= -3x
-3x=6
6/-3
x=-2
Add 6 to both sides and divide both sides by 5
