Answer:
No real solutions;

Step-by-step explanation:
The easiest method to solve an algebraic equation is to use inverse operations. This applies to the given equation;

- Take the square root of both sides
==================================================================
As one can see, the right side is a negative number. However, one cannot take the square root of a negative number and get a real result. Therefore, one must use imaginary numbers. Remember, the imaginary unit (
) represents (
).
==================================================================

- Add (3) to undo the (-3)

- Divide by (2) to remove the coefficient of (2x)
÷
÷

Simplify,

Answer:
8
Step-by-step explanation:
8(2) - 2(4)
16 - 8
8
Answer:
False
Step-by-step explanation:
The equation of any circle is 2πr or 2(3.14)1 in this question.
So 2x3.14= 6.28x1=6.28
The greatest common factor is 4
Strong and positive.
