Answer:

We get the final answer of -4x + 6

Step-by-step explanation:

Let's simplify step-by-step.

2x −3(2x−2)

Distribute:

= 2x+ (−3)(2x) + (−3)(−2)

= 2x+ −6x + 6

Combine Like Terms:

= 2x + −6x + 6

= (2x + −6x) + (6)

= -4x + 6

Identifying the reference angles

Tema [17]

A reference angle is the angle closest to the x-axis from the given angle.
Also called t-bar, a t with a bar over it. Reference angles are always POSITIVE.

Theta = 300, you can continue around to 360, or go back to 180. Going to 360 would be 60 degrees and going back to 180 would be 120 degrees. Therefore, the reference angle would be 60 degrees.

Theta = 225: 360 - 225 = 135; 225-180 = 45; t-bar = 45 degrees

Theta = 480; This angle has already made a full revolution (360) and is on the second revolution. It is coterminal to 120 degrees. 180-120 = 60 degrees;
120-0 = 120 degrees. t-bar = 60 degrees.

Theta = -210. -120 just means you are moving clockwise instead of counterclockwise.
180-120 = 60 degrees; 120- 0 = 120 degrees; t-bar = 60 degrees

The speed of light is approximately 299,800,000 m/s. How many hectometers will light travel in

frosja888 [35]

Answer:

To start with, we have to define the value of a hectometer. The question says that

a meter = 0.01 hectometer. This means that

a hectometer = 100 meter.

If the speed of light is 299,800,000 m/s, then converting to hectometer, we have the speed of light to be 2,998,000 hm/s

Going further, we are going to convert seconds to month.

1 minute = 60s

1hr = 60 min = 60 * 60 s = 3,600s

1 day = 24hrs = 3,600s * 24 = 86,400s

1 month = 31 days = 86,400 * 31 = 2,678,400s

this gotten value of 2,678,400 seconds is then multiplied by the hm/s we have earlier

2,998,000 * 2,678,400 = 8,029,843,200,00 hm/m or in standard form as

8 x $10^{12}$ hm/m
