Answer:
the anser is 24,32,56
Step-by-step explanation:
i did it got it wrong and then it gave me the right anser witch is that
area of playground= 9×15= 135m^2
area of lawn= 3×4=12m^2
total flooring area= 135-12= 123m^2
cost=36×123=$4428
-6x^2+4x
my reasoning:
eliminate the opposites (5 & -5)
collect the like terms (-8x^2 & + 2x^2)
collect the like terms again (-3x &+7x)
Answer: if you divide 15.55 by 5 the unit price is $3.11
