Answer:
0.54545454
Step-by-step explanation:
We have
x² + 24x = 17 (1)
Note that
(x + 12)² = x² + 24x + 144
By adding 144 to the left side of equation (1), it becomes a perfect square.
Therefore
x² + 24x = (x+12)² - 144 (2)
Substitute (2) into (1).
(x + 12)² - 144 = 17
(x + 12)² = 17 +144
(x + 12)² = 161
Answer:
We added 144 to the left side of equation (1) in order to make it a perfect square.
Well because they want 1000 dollars profit they need the inequality "15x is greater than or equal too 1700 dollars" But overall if you divide 1700 by 15 and round up on the decimal you get 114. So 114 is your answer.
