3. answer is 360
the reason I did this was because if you had multiplied math, physics and chemistry by 20 it would have given you the total of 800 trials
Answer:
B. a = 4, b = -8, c = -3
Step-by-step explanation:
The quadratic equation given is:

The general form of a quadratic equation is given as:

Let us put the given equation in this form and then compare with the general form of the quadratic equation.

Therefore, by comparing:
a = 4
b = -8
c = -3
The correct option is B
"Product" signifies multiplication, and "half" means divide by two (or multiply by 1/2). So half the product of b and c is (bc)/2 or (1/2)(bc).
