Answer:
hmmmmm i dont rlly understand this but ima guess tho i think a and c or d
Step-by-step explanation:
I'm going to say for this one it's going to be 46% Notice that the word percent has the word "cent", meaning a hundred. So "per hundred". We have 46 out of 100 here, so 46/100, and we can simplify to 23/50. Hope this helps.
Answer:
Since b^2 -4ac = 256 we have 2 real distinct root roots
Step-by-step explanation:
4x^2+12x=7
We need to subtract 7 to get it in the proper form
4x^2+12x-7=7-7
4x^2+12x-7=0
The discriminant is b^2 -4ac
when the equation is ax^2 +bx+c
so a =4 b=12 and c=-7
(12)^2 - 4(4)(-7)
144 +112
256
If b^2 -4ac > 0 we have 2 real distinct roots
If b^2 -4ac = 0 we have one real root
If b^2 -4ac < 0 we have two complex root
Since b^2 -4ac = 256 we have 2 real distinct root roots
<span>Though prices have never been higher at 427 to 434 reais (US$132-$134) per bag for conilon, the variety of robusta grown in Brazil, producers expect another bad crop in 2017 as they tear up trees ruined by drought. At current prices, Brazil's 2016 robusta crop is worth $1.2 billion.</span>
