<span>-2x^2-x+7=0
Variable with the highest degree's (exponent) constant, -2 is a, next variable's constant, -1 is b, the constant or number without a variable, 7 is c
using substitution put the numbers into the formula
</span>(-b±√(b^(2)-4ac))/(a^(2))
(-(-1)±√((-1)^(2)-4(-2)(7))/((-2)^(2)) simplify
(1±√(1+56))/4
1±√(57)/4 is your answer
So we need to compare them at the sam ounches
find the least common multiple (the smallest number that they will both multiply into)
first find the factors and group them all together, delete any repeats
6=2*3
8=2*2*2
least common multiple=2*2*2*3=24
so 6 bags=2.46
multiply by 4 to get 24
24 bags=9.84
so 8 bags=3.20
multply by 3
24 bags=9.60
9.84>9.60 so
the 8 ounce bag is less expensive
The 13th amendment because This amendment abolished slavery and involuntary servitude. For what’s happening now I think we need this amendment added to the constitution right now because a lot of people are dying for their race. Not only that but they also get accused of things that aren’t even they don’t know what happened. And it’s really sad because some people get plastic surgery because of their skin. For example Michael Jackson.
For x such that 0 < x < 
, the mathematical expression is:
