Answer:
x = 8
Step-by-step explanation:
30x = (60)(40)
30x = 240                 Multiply 60 and 40
x = 8                          Divide 30 from both sides

Answer:

Step-by-step explanation:
The equation  represents the discriminant of a quadratic. It is the part taken from under the radical in the quadratic formula.
 represents the discriminant of a quadratic. It is the part taken from under the radical in the quadratic formula.
For any quadratic:
- If the discriminant is positive, or greater than 0, the quadratic has two solutions
- If the discriminant is equal to 0, the quadratic has one distinct real solution (the solution is repeated).
- If the discriminant is negative, or less than 0, the quadratic has zero solutions
In the graph, we see that the equation intersects the x-axis at two distinct points. Therefore, the quadratic has two solutions and the discriminant must be positive. Thus, we have  .
