I don't quite see any extraneous solutions, other than, the root is an even root, root of 2, and therefore, it will give you a ± solutions, if x = 6, the radicand becomes 0 then, and the roots for that will be ±0, keeping in mind 0 is neither per se.
now on the right-hand-side, 6-6 is just a flat positive 0, so the +0 root will match that, however the -0 will not, and thus can be seen as extraneous.
Answer:
22
I think you just add them because when you draw them out, the points form the line TV.
<span>In order to calculate compounded interest, we use the formula: Final amount = initial amount x (increase rate)^(time periods). We know that the interest rate is 6%, so the factor we multiply by is 1.06. Moreover, the interest is compounded twice per year. This means that there will a total of 2 x 10 = 20 time periods over which the amount is compounded. Therefore, the final amount works out to be: Final amount = 200(1.06)^20, which is equivalent to $641.</span>
To find an equivalent fraction, you can just easily multiply the numerator and the denominator by anything.
6/10 and 300/500 are equal, because I multiplied each by 2 and 100, respectively.
