So 16=heads
18=tails
after you add some tails
18+x
ratio of heads to tails is 1:1.5
heads=16, didn't change
tails=18+x
so
1:1.5=16:18+x
fractionify
1/1.5=16/(18+x)
1/1.5=2/3
2/3=16/(18+x)
mutiply both sides by (3)(18+x)
2(18+x)=3(16)
36+2x=48
subtract 36 from both sides
2x=12
divide 2
x=6
6 tails added
total=heads+tails
heads=16
tails=18+6=24
total=16+24
total=40
6 tails added
40 total coins
Answer:
(D)(x-2)(x+2)
Step-by-step explanation:
As raízes do polinômio são 2 e -2, portanto sua forma fatorada tem que ser (x-x1)(x-x2) se x1=2 e x2=-2. Então:
p(x) = (x-2)(x+2)
