(2x-4)(x+5) expand with indicated multiplication...
2x^2+10x-4x-20
2x^2+6x-20 (it's the top one :P)
X^4 - 4x^3 - 9x^2 + 36x = 0
x(x^3 - 4x^2 - 9x + 36) = 0
x(x^2(x - 4) - 9(x - 4) = 0
x(x + 3)(x - 3)(x - 4) = 0
the zeroes are -3, 0, 3, 4 Answer
Answer:
25%
Step-by-step explanation:
Step one:
A store normally sells certain dress for $160 during a special sale
the store reduces the price of the dress to $120
Step two:
Percent reduction= change in price/initial price *100
Percent reduction= 160-120/160 *100
Percent reduction= 40/160*100
Percent reduction==0.25*100
Percent reduction=25%
