Answer:
your rue
Step-by-step explanation:
Differnce of 2 pefect squares
a^2-b^2=(a-b)(a+b)
(p^2)^2-9^2=(p^2-9)(p^2+9)
p^2-9=(p-3)(p+3)
factored is
(p-3)(p+3)(p^2+9)
1/4 of 8 is 2. So 2 of the cubicles are carpeted.
U/72 = 2/4
means u/72 = 0.5
therefore u = 72*0.5
which equals 36
Well, the first one is 2/40=1/20. The 2nd one is 1/39. You multiply these to get 1/780.
