Answer:
x is equal to 2.5 and -4.5
Step-by-step explanation:
-4(x + 1)² - 3 = -51
-4(x² + 2x + 1) - 3 = -51
-4x² - 8x -3 - 3 = -51
-4x² - 8x - 6 = -51
-4x² - 8x = -45
-4(x^2 + 2x) = -45
-4(x^2 + 2x + 1) = -49
-4(x + 1)² = -49
(x + 1)² = 49/4
x + 1 = ± √(49/4)
x + 1 = ± 7/2
x = -1 ± 3.5
x = 2.5, -4.5

<em>Hi there!</em>
<u><em>For 1. it should be answer b</em></u>
<u><em>For 2. it would be answer c</em></u>
<u><em>For 3. it is answer a</em></u>

Let A be the event
and B be the vent
. Since the intersection of the events
, the events A and B are mutually exclusive.
The number is either odd or even. Since
, the events are mutually exclusive and exhaustive.
Correct choice is "the number is either odd or even".
