Answer:
Step-by-step explanation:
The slopes of the two lines (representing the speeds of the trains) are the same, and so the two trains are traveling at the same speed.
Answer: 2x+1
Notice how the 2x in the answer and the x, from x+6, multiplies to 2x^2
Also the 1 from the answer and the 6 from x+6 multiplies to 6
The results of 2x^2 and 6 are the first and last terms respectively of the original trinomial. None of the other answer choices fit this.
You can use the FOIL or box method to get
(x+6)*(2x+1) = x*(2x+1)+6*(2x+1)
(x+6)*(2x+1) = 2x^2+x+12x+6
(x+6)*(2x+1) = 2x^2+13x+6
which confirms the answer is 2x+1
The solution to the expression 
gives (x + 4)/2

Answer:
(3,8)
Step-by-step explanation:
y - 5 = x
4x - y = 4
Since y-5 = x, substitute y-5 in place of x in the second equation:
4x- y = 4
4(y-5) - y = 4
4y - 4*5 - y = 4
3y - 20 = 4
3y = 24
y =8
Solve for x:
y - 5 = x
8-5 = x
3 = x
Check:
4x - y = 4
4(3) - 8 = 4
12 - 8 = 4
4 = 4
Check
y - 5 = x
8 - 5 = 3
3 = 3
Check!
