Which graph shows the solution set of x^2+9+20/x^2-x-20 > 0

Before we do anything, we can factorize the numerator and denominator:

(the cancellation is valid as long as ; is not even in the domain of the right hand side, so we're good here)

Then

6mm^3 or .6cm^3

      216

      /   \

  36     6

  /   \     /

6     6   6

factor trees are nice.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
