X² + 4x – 32
x2 + x - 20

1.  (x+8)(x-4)

2.  3x-20

Step-by-step explanation:

1.  x² + 4x – 32

x² + 8x - 4x - 32

x (x+8) - 4 (x+8)

one of the x+8's is cancelled out then you have (x+8)(x-4)

2.  x2 + x - 20

2x+x-20

3x-20

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.
