All of the following are equivalent to 2(2a + b) + 8, except . 4 a + 2 b + 8
2(2 a + b + 4)
4( a + b + 2)
4 a + 2( b + 4)

C. 4(a + b + 2)

Step-by-step explanation:

2(2a + b) 8 equals 4a + 2b + 8.  4(a + b + 2) equals 4a + 4b + 8

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
