Answer:
n = -2
Step-by-step explanation:
Eliminating parentheses, you have ...
2n +6 -6n = 14
Combining terms and subtracting 6, you get ...
-4n = 8
Dividing by the coefficient of n gives ...
n = -2
_____
<em><u>Check</u></em>
2(-2) +3(2 -2(-2)) = 14
-4 +3(2+4) = 14
-4 +3(6) = 14
-4 +18 = 14 . . . . answer checks OK
Answer:
Red = 25/32768
Blue = 4/64
Step-by-step explanation:
Green Marbles = 1
Red Marbles = 5
Blue Marbles = 2
Probability of picking a red marble = 5/8 x 5/8 x 5/8 x 5/8 x 5/8 = 25/32768
Probability of picking a blue marble = 2/8 x 2/8 = 4/64
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 (
).
