-3• f(-8)+ 7•g(2)

A. -18
B.-20
C. -22
D. -30

Please help!!!

C -22

Step-by-step explanation:

-3• f(-8)+ 7•g(2)

f-(8) = -2

g(2) = -4

-3 * -2 +7(-4)

6 -28

-22

final answer is : )

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.
