The answer is x²-8x+13=0
Here is how:
[x-(4+√3)][x-(4-√3)]=0
expand and simplify:
x² -(4-√3)x - (4+√3) +(4+√3)(4-√3)=0
x²-8x+13=0

Reggie has $36.40 in nickels and $36.40 in dimes. What is the ratio of the number of nickels to the number of dimes that Reggie
Dmitry [639]

D 2:1, because a dime is worth twice as much as a nickel

Because the question has number of nickels listed first in the ratio that makes the answer 2:1 as opposed to B 1:2. Also, two nickels equal the same amount as one dime so for every two nickels there is one dime. In this case, there are 728 nickels and 364 dimes. 728/364 = 2/1 (simplifies down to the fourth ratio given)

Convert the fraction 7 24 into a repeating decimal.
goldenfox [79]
\dfrac7{24}=\dfrac6{24}+\dfrac1{24}=\dfrac14+\dfrac1{24}

\dfrac1{24}=\dfrac1{8\time3}=\dfrac a8+\dfrac b3=\dfrac{3a+8b}{24}
\implies3a+8b=1

We can choose a=-1 and b=\dfrac12, so that

\dfrac1{24}=-\dfrac18+\dfrac16

Recalling that \dfrac13=0.333\ldots, it follows that \dfrac16=0.166\ldots. So,

\dfrac1{24}=0.125+0.166\ldots=0.04166\ldots
\implies\dfrac7{24}=0.25+0.4166\ldots=0.29166\ldots
