Answer:
x = -6 , -2
Step-by-step explanation:
Find factors of x² and 12, in which, when combined, will give 8x:
x² + 8x + 12 = 0
x 6
x 2
(x + 6)(x + 2) = 0
Check. Use the FOIL method:
First, combine the first terms: x * x = x²
Next, combine the outside terms: x * 2 = 2x
Then, combine the inside terms: 6 * x = 6x
Finally, combine the last terms: 6 * 2 = 12
Combine like terms: x² + (2x + 6x) + 12
x² + 8x + 12
Solve for the solutions. Set each parenthesis equal to 0:
(x + 6)(x + 2) = 0
(x + 6) = 0
(x + 2) = 0
Isolate the variable x. Subtract 6 & 2 from both sides for their respective equation:
x + 6 = 0
x + 6 (-6) = 0 (-6)
x = 0 - 6
x = -6
x + 2 = 0
x + 2 (-2) = 0 (-2)
x = 0 - 2
x = -2
x = -6 , -2

Question s Incomplete; Complete question is given below;
There is a mound of g pounds of gravel in a quarry. Throughout the day, 400 pounds of gravel are added to the mound. Two orders of 900 pounds are sold and the gravel is removed from the mound. At the end of the day, the mound has 1,500 pounds of gravel. Write the equation that best describes the situation.
Answer:
The equation that best describes the situation is .
Step-by-step explanation:
Given:
Amount of gravel present initially = ''.
Now Given:
Throughout the day, 400 pounds of gravel are added to the mound.
So we can say that;
Amount of gravel after addition =
Also given:
Two orders of 900 pounds are sold and the gravel is removed from the mound.
Now Two orders of 900 pounds =
So we can say that;
Amount of gravel after removing =
Now Given:
Amount left in mount at the end of the day = 1300 pounds.
So we can say that;
Hence the equation that best describes the situation is .
2 weeks = 14 days.
21 hours × 14 days = 294 hours total.
8.8 watts × 294 hours = 2587.2 Wh or 2.5872 kWh.
Answer:
I think yes because u will have 760 leftover
