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.
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
.

Billion has 9 zeros.
Let Jane use 'X' lace.
Then,
Marcus uses '3X' lace [ according to the question]
Here,
X + 3X = 64
4X = 64
X = 16
So, Jane uses 16 laces and
Marcus uses 3*16 = 48 laces
