I believe it would take you 7 hours at that miles per hour
Answer:
A.
Step-by-step explanation:
The answer is A because well 3x would not change and 17x would not change but 7 and 5 would change because they are not variable numbers So when u do the mah you would get 3x2+17x -2
As, synthetic division by -4 gives remainder 0. Hence, Option B is correct. -4 is a root of 
As, x+4=0 gives x=-4.
So, option C is correct,
(x+4) is factor of 
Option E is correct

Answer:
<h2>x = 7 cm</h2>
Step-by-step explanation:
The perimeter of the given triangle:
P = (2x + 1) + (x + 2) + (3x - 9) and P = 36 cm.
Therefore we have the equation:
2x + 1 + x + 2 + 3x - 9 = 36 <em>combine like terms</em>
(2x + x + 3x) + (1 + 2 - 9) = 36
6x - 6 = 36 <em>add 6 to both sides</em>
6x = 42 <em>divide both sides by 6</em>
x = 7
