The answer is: k^{2} /2

 The explanation is shown below:
 1. You have the following expression given in the exercise above:
 ( 4k^{2}) /(2k+3)(2 k^{2} -5k-12)/(8k-32)

 2. By applying the distributive property, you obtain:
 (8k^{4}-20k^{3}-48k)/(16k^{2} -40k-96)
 3. Now, you must factor k^{2} in the numerator and 2
 in the denominator:
 k^{2}(8 k^{2} -20k-48)/2(8 k^{2} -20k-48) 
 4. Simplify:
 k^{2} /2

dalvyx [7]

Gallons of water are leaked in one year is 94.253 gallons

<h3><u><em>Solution:</em></u></h3>

Given that leaky faucet drips 356,755 mL of water over the course of the year

There are approximately 3,785 mL in 1 gallon.

To find: gallons of water are leaked in one year

From given information,

Amount of water leaked in one year in ml = 356,755 mL

Also given in question that,

<h3>1 gallon = 3785 ml</h3>

1 \text{ ml} = \frac{1}{3785} \text{ gallons}

<em><u>Now we can convert 356,755 mL to gallons</u></em>

356,755 \text{ ml} = \frac{1}{3785} \times 356755 \text{ gallons}\\\\356,755 \text{ ml} = 94.253 \text{ gallons}

Thus gallons of water are leaked in one year is 94.253 gallons

First of all, we need to open parentheses:

-4b-9k-6-3b+12

Next, combine like terms:

-4b-3b-9k-6+12 \\ \\ \therefore \boxed{-7b-9k+6}

Adam is 159 centimeters tall and casts a shadow 105 centimeters in height. If Cara is 140 centimeters tall, how many centimeters
vodomira [7]

Answer:

The answer to your question is 12.55 cm

Step-by-step explanation:

Data

Adam                                  Cara

height = 159 cm                  height = 140 cm

shadow = 105 cm                shadow = x

Process

1.- To solve this problem use the Thales' theorem

         Cara's shadow / Cara's height = Adam's shadow / Adam's height

- Substitution

                                     x / 140 = 105 / 159

-Solve for x

                                     x = 105 (140) / 159

-Simplification

                                     x = 14700 / 159

                                     x = 92.45 cm

Cara's shadow is 92.45 cm long.

2.- If both shadows are in line, then Cara must walk forward

                105 - 92.45 cm

                12.55 cm
