.4=2/5
80=2
X =5
2x=400
X=200
(x+1)(x-4)-(x-2) = 0
x²-4x+x-4-x+2 = 0
x²-4x-2 = 0
/\ = (-4)² - 4*1*(-2)
/\ = 16 + 8
/\ = 24
x = (-(-4)+/- \/24) / 2
x = (4+/-\/4*6)/2
x = (4+/-2\/6)/2
x = 2+/-\/6
x' = 2+\/6
x" = 2-\/6
Answer:
true
Step-by-step explanation:
Rounding is important, because you could have endless quotients.
For example, 10 / 3.3 = 3.3333333333333333333333333333333333333.
It is recommended that you stop at the hundreths place and round.
