Answer:
The correct answer is f(x)
Step-by-step explanation:
The answer is f(x) because is the result of the quadratic sum, once the function is evaluated. Example:
Let be x= 2
Then f(2)= 4+2+1=7
Therefore the output is f(2) which is equal to 7.
Answer:
x=60
Step-by-step explanation:
The sum of interior angles of a regular Pentagon is 540°
x+2x+2.5x+x+10+2x+20=540
8.5x=540-30
8.5x=510
x=510/8.5=60
The answer is <u>22.5</u>
