The discriminant, b^2 - 4ac, will tell you how many and what type of solutions you have in a quadratic equation.
a= 2 b= -3 c= 1
(-3)^2 -4*2*1
9-8=1
Since the discriminant is a positive real number, there will be two real solutions,
So the graph will cross the x axis in two places. The answer is A

QveST [7]

Answer:

13500

Step-by-step explanation:

to answer this question

  1. convert the dimensions of the field to foot
  2. find the area of the field
  3. divide the area by the space of each egg

1 yard = 3 foot

75 yards = 75 x 3 = 225

120 yards = 120 x 3 = 360 ft

Area of a rectangle = length x width

225 x 360 = 81,000 ft^2

Maximum number of eggs = Area of the field / space the eggs must be apart

81,000 / 6 = 13,500

3x - 20 = 4x ( subtract 3x from both sides )

- 20 = x
