Step-by-step explanation:
Exact form: 169/28
decimal form: 6.03571428
mixed number form: 6 1/28
If xy=0
assume that at least x or y=0
3(x-3)=0
therefor
3=0 or x-3=0
3=0 is false
therefor
x-3 mus equal zero
x-3=0
add 3 to both sides
x=3
The answer is negative 4...4 to 0 has the same distance as -4 to O
