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
<span>you can turn 3.6 into a fraction, and then switch the numerator and denominator: 3.6 = 3.6/1 = 36/10
the reciprocal is
10/36 = 5/18
reduced the fraction by dividing the top and bottom by 2
you could ALSO say the reciprocal of:
3.6/1 is 1/3.6,
but i assume you're supposed to come up with a nice fraction...</span>
What times what = 36 like two of the same numbers. then multiply that number by 4 for the number of sides and u get the perimiter. (sry if confusing so ill explain that 6×6=36)
<span>a+s=566
s=a+66
a+a+66=566
</span>2a=500<span>a=250
c=250+66 </span>
