Hello there!

The one is asking lot of hard work and I don't know how to write the quadratic formula so I can't show the work for this one.
The answer is : two solutions

#2
Number two is easy to show my work
0 = 3x² + 18x + 27
-3x² - 18x - 27 = 0
Now all we have to do is factorize
-3(x + 3)(x + 3) = 0
Now set each factors equal to 0
x + 3 = 0 or x + 3 = 0
x = - 3
The correct option is A - One solution

A+ Guaranteed! If you have further question or misunderstand the steps please feel free to ask.

Have a nice day!

Find the probability.
kvv77 [185]

Answer:

7/36

Step-by-step explanation:

1 die has 6 faces

When two dice are rolled, the total number of outcomes

= 6 × 6 = 36

The Probability of having(5) =

(1 & 4), (2 & 3) , ( 3 & 2), (4 & 1)

= 4

The probability of having (10) =

(5 & 5), (4 & 6) , ( 6 & 4)

= 3

The probability that the score on the dice is either 5 or 10.

P(5) + P(10)

= 4/36 + 3/36

= 7/36

How can you use the graph to f he amount of distilled water to use for 4.5 milliliters of ammonia?
Elden [556K]

Answer:

The graph can show you how much distilled water for 4 milliliters of ammonia and 5 milliliters of ammonia. You can use the graph to find 4.5 by find the midpoint of two amounts of distilled water. Such as, say that 4 milliliters of ammonia = 200 distilled water and 5 milliliters of ammonia=  250 distilled water. Then the answer to 4.5 milliliters of ammonia is 225 distilled water.
