Answer:
3.9230231e+12
Step-by-step explanation:
15! is 15 times 14 times 13 times 12 times 11 times 10 times 9 times 8 times 7 times 6 times 5 times 4 times 3 times 2 times 1 then times 3 because 3 shades of blue.
(x−1)²−9=0
(x-1)²= 9
x-1 = ±√9
x-1 = ±3
x = 1-3=-2 or x=1+3=4
the solution = {-2,4}
33 newspapers per 1 pile.
33+33+33=99
360 people
x = 0.8x + 72 Subtract 0.8x on both sides
0.2x = 72 Divide 0.2 on both sides
x = 360
I think 543,2=24.
hope it helps
