If our equation is $a = 3400t + 600$ , and we have a target altitude of $21,000$ , we just need to plug that in for $a$ .

$21,000 = 3,400t + 600$ . Now subtract $600$ from both sides.

$20,400 = 3,400t$ . now divide both sides by $3,400$ .

$6 = t$ .

We get that our answer is at 6 minutes we get an altitude of 21,000 feet!

Answer:

${x}^{2} + 4x - 9 = 5x + 3 \\ {x }^{2} - x - 12 \\ {x}^{2} - 4x + 3x - 12 \\ x(x - 4) + 3(x - 4) \\ (x - 4)(x + 3) \\ x = 4 \: and - 3$
