ANSWER
The correct answer is D.
EXPLANATION
If we express the monomial,

as product of primes, we obtain:

If we express the monomial

as product of primes we obtain:

The least common multiple of these two binomials is the product of the highest powers of the common factors.
The LCM is


Therefore the correct answer is D.
Step-by-step explanation:
For the quadratic equation to have 1 repeated real solution, the discriminant b² - 4ac must be zero.
=> (-z)² - 4(z - 5)(5) = 0
=> z² - 20(z - 5) = 0
=> z² - 20z + 100 = 0
=> (z - 10)² = 0
Therefore z = 10.
Answer:
If you add 690 ml of water you will obtain 1.690 liter of 70% alcohol. Of course if you halve the amounts, e.g. 0.5 liter 75% alcohol and 345 ml of water, you will also obtain 45% alcohol solution.
