D. (4√(2) - √(2)) × √(2) + (2) × √(18)
3√(2) × √(2) + 2√(2) × 3√(2)
3(2) + 6(2)
6 + 12
18
E. √(3) × (2√(5) + 3√(5)) - √(5) × (√(3) + 2√(3))
√(3) × 5√(5) - √(5) × 2(3)
√(3) × 5√(5) - √(5) × 6
5√(15) - 6√(5)

Answer:
A bi conditional statement is a combination of a conditional statement and its converse written in the if and only if form. Two line segments are congruent if and only if they are of equal length
Step-by-step explanation:
X = amount of the 18% solution
y = amount of the 40% solution
we know the 18% solution has only 18% of alcohol, the rest is maybe water or something, now, how many liters is 18%? well, 18% of anything is just (18/100) * anything, so, 18% of x is just (18/100) *x or 0.18x, and that's how many liters are there.
likewise, how many liters are there in the 40% solution? well, (40/100) * y, or 0.4y, that many.
we know the mixture has to yield 10 liters at 20% alcohol, how many liters of only alcohol is that? well, (20/100) * 10, or 2 liters.


how much of the 40% solution? well y = 10 - x
