Answer:
The negative solution is -2
Step-by-step explanation:
Let the number be x
x² - 16 = 6x
Equate the equation to zero (0)
x² - 6x -16 = 0
Factorize
x² + 2x -8x - 16 = 0
x(x + 2) -8(x + 2) = 0
Therefore,
(x-8) (x +2) = 0
x -8 = 0 or x +2 = 0
x = 8 or x = -2
The negative solution is -2
Answer:
72 parts
Steps:
Convert the 4 hours into minutes. There are 60 minutes in an hour. Therefore, 4 hours = 240 minutes.
Divide 240 minutes by 40 minutes. This equals 6. Therefore, the machinist can produce the 12 parts 6 times in 4 hours.
Finally, multiply the 12 parts by the 6 times he can produce. Therefore, the machinist can produce 72 parts in 4 hours.

Answer:
t + 8 = 82
Step-by-step explanation:
I believe they want the temperature at 11, so we would use the variable t to represent that. Then, we need the sum of that temperature and 8 degrees to break the record of 82 degrees, so we would do t, the temperature, added to 8 degrees, which will break the record of 82 :)
