Answer:
14
Step-by-step explanation:
I first multiplied 490 by 3/7
giving me 1470/7
I divide 1470 by 7 giving me 210
As I got 210
I multiplied 210 with 2 and got 410/3
I divided 410 by 3, getting 140.
It then said half of what was delivered was put into 5 pound bags, so
140× 1/2 or 140÷2 is 70
70 divided by 5 is 14
They made 14 5-pound bags.
Answer:
x=9
Step-by-step explanation:
This is a polynomial with more than 2 as a degree. Using Descartes Rule of Signs:
f(x) = x⁶ + x⁵ + x⁴ + 4x³ − 12x² + 12
Signs: + + + + − + 2 sign changes ----> 2 or 0 positive roots
f(−x) = (−x)⁶ + (−x)⁵ + (−x)⁴ + 4(−x)³ − 12(−x)² + 12 f(−x) = x⁶ − x⁵ + x⁴ − 4x³ − 12x² + 12
Signs: + − + − − + 4 sign changes ----> 4 or 2 or 0 negative roots
Complex roots = 0, 2, 4, or 6
