Find the perimeter. Simplify your answer.
6+3
6+3
80-3

Step-by-step explanation:

Perimeter= 6u+3+6u+3+8u-3= 20u+3

(6u+3)+(6u+3)+(8u-3)

=6u+3+6u+3+8u-3

=20u+3

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.
