Answer:
Step-by-step explanation:
Absolute Value of the number is the distance of the number from zero on the number line. Thus, the absolute value of -8 and 8 is the same i.e. 8.
That means, the absolute value of negative or positive of that number is always a positive number of that number.
∵ is a positive number.
So, absolute value of is .
11
4+4+.1*(15+15)=11
-2x² + 5x - 3 - (-7 - 9x + 5x²)
= -2x² + 5x - 3 + 7 + 9x - 5x²
= -7x² + 14x + 4.
Hence the coefficient of the x term is 14.
