V30% mixture + v100% mixture = v60% mixture

0.3(10-x) + x = 0.6(10)
3 - 0.3x + x = 6
0.7x = 6 - 3
0.7x = 3
x = 3/0.7
x = 4.286 quarts

Solve by factoring g^2-14s+45=0​
Andrej [43]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ First find two values that multiply to make 45 but add to make -14

As you will figure out through trial and error, it is -9 and -5

Factorize it with these values:

(g - 9)(g - 5)

The actual values for g would be the opposite of what is in the parenthesis

Therefore, g = 9, or g = 5

Need help for #9 please

Ok as sqrt(x^6 + 5) approaches infinity it goes to x^3
Same with the denominator because x^3 is the highest power

On the bottom, the factor on x^3 is 4 so on the top to make the limit evaluate to 1/3, a has to be 16/9 so then when you neglect all of the other powers besides the highest, it goes to 4/3 because you take the square root and then it simplifies to 1/3

So,

We see in Statement 3 that WY = WY.  This seems obvious, but it ensures that quantities don't change their values.  We call this property of something being equal to itself, the "reflexive property."

The correct answer is the third option.
