everything except the last two, I think.
Answer:
4+i
Step-by-step explanation:
A complex number usually took the form a+bi where a and b are real numbers and 'i' represents an imaginary number. For a quadratic equation, the complex roots for the root of a quadratic equation took the form known as complex conjugates. The complex conjugates are formed by changing the sign of the imaginary part.
SO, if a quadratic equation has 4-i as a solution, the other solution must be 4+i.
Circle = pi*r^2
Diameter = 80, so radius = 40
Circle = pi*40^2 = pi*1600 is approximately 5026.55 yards
400,000 + 50,000 + 700 + 5
