Answer:
A
Step-by-step explanation:
The opposite angles in a parallelogram are congruent, thus
∠ C = ∠ A = 57°
<span>Simplifying
14x + -21xy
Factor out the Greatest Common Factor (GCF), '7x'.
7x(2 + -3y)
Final result:
7x(2 + -3y)
that is the answer on how to do it</span>
Answer:
its 65
Step-by-step explanation:
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)
