θ\ 6 degrees
\
\ so the θ= 180-90-6 =84 degrees so we need to find x
20m \ tan (84)=x/20
____ \ x=20 tan(84)
x x=190.287
Let x be the number.
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
The question can be solved as follows:

Hence the value of the given expression in scientific notation is expressed as:
Answer:
hope the attached picture gives the answers
Answer:
It is a function
Step-by-step explanation:
This isn't really a step by step explanation but I'm going to explain this simply. An output can have as many inputs possible but an input can only have ONE OUTPUT(just putting emphasis on this one output, I'm not yelling). Example, the input "2" can be equal to the output of "4" depending on the equation the fuction, however, the input of "2" CAN NOT be equal to the outputs of "4" and "6" because as my Algebra teacher explained it "for every input, there is exactly one output". I hope this helps and I hope I didn't lose you in my explaination.
