3) 500
4) 4,000
5) 9
6) 600
7) 7,000
8) 200,000
9) 2,000 * 10 = 20,000. 20,000 * 10 = 200,000.
D 28/4=7 that is the answer for the question
That should be the answers
Answer: There are no real number roots (the two roots are complex or imaginary)
The discriminant D = b^2 - 4ac tells us the nature of the roots for any quadratic in the form ax^2+bx+c = 0
There are three cases
- If D < 0, then there are no real number roots and the roots are complex numbers.
- If D = 0, then we have one real number root. The root is repeated twice so it's considered a double root. This root is rational if a,b,c are rational.
- If D > 0, then we get two different real number roots. Each root is rational if D is a perfect square and a,b,c are rational.
Since "chair" probably means "share", John will have 2 2/3 slices of pizza left.
The 12 slice pizza is split between 3 people, so each person gets 4 slices. John only eats 2/3 of his 4 slices, and 2/3 of 4 is 2 2/3.
