The answer is 3x^2-19x+1

(-4x+3)-(7x-3x^2-1)
-12x+7x+3x^2+1

Combine like terms:
3x^2+(-12x+-7x)+1
= 3x^2+-19x+1

At maximum speed, an airplane tracked 1720 miles against the wind in 5 hours. Flying with the wind, the plane can travel the sam
nataly862011 [7]
Recall your d = rt, distance = rate * time.

as the plane goes against the wind, the plane is not really flying at "x" mph, but is really going slower, at " x - y ", because the wind is subtracting speed from it.

likewise, when the plane is going with the wind, is not really going at "x" mph, but at " x + y ", is going faster due to the wind, thus

\bf \begin{array}{lccclll}&#10;&\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\&#10;&------&------&------\\&#10;\textit{against the wind}&1720&x-y&5\\&#10;\textit{with the wind}&1720&x+y&4&#10;\end{array}&#10;\\\\\\&#10;\begin{cases}&#10;1720=(x-y)5\implies \frac{1720}{5}=x-y\\\\&#10;344=x-y\implies \boxed{y}=x-344\\&#10;---------------\\&#10;1720=(x+y)4\implies \frac{1720}{4}=x+y\\\\&#10;430=x+y\implies 430=x+\left( \boxed{x-344} \right)&#10;\end{cases}&#10;\\\\\\&#10;430=2x-344\implies 774=2x\implies \cfrac{774}{2}=x\implies 387=x
