Answer:
Step-by-step explanation:
-2x²=-8x+8 means : -2x²+8x-8
the discrinant of the quadratic equation is : delta = b²-4ac
when a=-2 and b=8 and c= -8
calculate delta = (8)²-4(-2)(-8) ......continu

$4.55 Add 5.95 and 9.76. You should get 15.45. Then you do 20-15.45=4.55
Answer:
Depends on what way you learnt it
Step-by-step explanation:
x + y = 4. x^2 + y^2 = 28. These are the given equations.
Square the first equation to get x^2 + 2xy + y^2 = 16.
Subtract the new equation from x^2 + y^2 = 28 to get 2xy = -12.
Divide by 2 to get xy = -6. The questions asks for positive numbers, and a positive times a positive is not a negative, therefore there are no two numbers.
