Which expression demonstrates the use of the commutative property of addition in the first step of simplifying the expression (-1 + 1) + (21 + 5/)? (-1 + i) + (21+5i) + 0
-1 + (i + 21) + 5i
(-1 + 21) + (i + 5i)
-(1-i) + (21 + 5i)

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

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.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
