Answer:
x is equal to 0.94 and -1.94
Step-by-step explanation:
3x² + 3x + 7 = 0
9x² + 9x + 21 = 0
9x² + 9x + 2.25 = 18.75
(3x + 1.5)² = 18.75
3x + 1.5 = ±√18.75
3x = -1.5 ±√18.75
x = (-1.5 ±√18.75) / 3
x = 0.94, -1.94
-5 + 7= 7 + (-5) they are the same just switched

Answer:
2/5
Step-by-step explanation:
Let's find the probability of each condition first.
For P(4), there is only one option: 4. This is 1 out of 5.
For P(even), this includes 4 and 6. However, we already had 4 from our last condition so we can remove this option. This is again 1 out of 5.
Adding them together, we will get 2/5.
The answer is 2/5
