4x^2 + 4x + 3.
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 5x^2 - 3 - (x^2 - 4x - 6)
= 5x^2 - 3 - x^2 + 4x + 6
= 4x^2 + 4x + 3.

Answer:
Step-by-step explanation:
There are three reasons here why randomization is not being applied.
First, the coach is only observing football players attending the meeting. This is not representative of the entire team.
Second, there is no selection process. The coach isn't using a random generator or using a similar method.

Answer: 7
Step-by-step explanation:
1. multiply both sides by -6 so the -6 on the right side could cancel out and the left side would be -6: 1= a-13/-6 ==> -6=a-13
2. add both sides by 13 so -13 on the right side could cancel out and the left side would be -6+13: -6=a-13 ==> -6+13=a-13+13
3. you know -6+13 equals 7 right? so the answer is a=7
