Answer:
The mean temperature in Atlanta in July is less than or equal to 90 F
Step-by-step explanation:
x can have two complex solutions, which are:
-2 + i
-2 - i
2x² + 8x + 10 = 0
4x² + 16x + 20 = 0
4x² + 16x + 16 = -4
(2x + 4)² = -4
2x + 4 = √-4
2x = -4 ± i√4
2x = -4 ± 2i
x = -2 ± i
So x is equal to -2 + i and -2 - i.
