Answer:
Step-by-step explanation:
2x² + x -1 = 0
x² + x² + x -1 = 0
(x² - 1) + x² + x =0
(x + 1) (x - 1) + x(x + 1) =0
(x+1) (x - 1 + x) = 0
(x + 1)(2x - 1) = 0
The answer is $122.13
Explanation:
610 • 0.32 = 1,105.6
Then you’re going to add everything up:
650 + 260.40 + 260.40 + 16.95 + 11.56 + 10.56 + 17.84
And get =
1,227.73
And you’re going to subtract that with 1,105.6 and get the answer.
