Answer:
Solution not exists.
Step-by-step explanation:
Since in a certain step a certain amount divided by zero, an that stage the quentity is undefined. That is if,
Then, at the next stage, 
is not exists, wheather after it divided by 1 or not. Thus required solution is not exists.
D. is a difference of perfect squares because both terms 25x^2 and 36 is a square (5, x, and 6). Also, difference of perfect squares MUST have a minus sign.
The answer would be about $2.79
The important clue from the problem, would be (w/v). This would indicate that the percent has units of weight per volume. We calculate as follows:
Grams solute = .30 g solute / mL solution (450 mL) = 135 g of solute.
Hope this answers the question. Have a nice day.
Do 4 times $15 and 5 times $9. Add both of the answers together. That is the total cost.
