a+b=9 a+c=4 b+c=5 . Find a+b+c.

(A) 4 (B) 5 (C) 7 (D) 8 (E) 9

show your work please.
thanks!

(E) 9

Step-by-step explanation:

A= 4

B= 5

C= 0

a+b+c= 4+5+0= 9

a+b=9= 4+5=9

a+c=4= 4+0=4

b+c=5= 5+0= 5

the correct is answer is a 9-sided polygon!

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.
