Answer:

1 / (x² + 6x + 8)

Step-by-step explanation:

(x + 4) / (x² + 5x + 6) * (x + 3) / (x² - 16)

= (x + 4) / (x + 2)(x + 3) * (x + 3) / (x + 4)(x - 4)

               ↑ factor x² + 5x + 6    ↑ factor x² - 16 using difference of squares

= 1 / (x + 2) * 1 / (x - 4)    ← x + 4 and x + 3 cancel

= 1 / (x + 2) * (x + 4) ← multiply

= 1 / (x² + 6x + 8) ← expand

Answer:

Rise: 200.25

Descent 300.2

Minutes

Step-by-step explanation:

A)        We are using the Pythagorean theorem for the climb and descent. (a^2 + b^2 = c^2)

For climb a = 200, b = 10 c = ?

200^2 + 10^2 = c^2 = 40000 + 100 = c^2 = 40100 = c^2

c = about 200.25

For the descent: a = 300, b = 10

300²+10² = c²

90000 + 100 = c²

90100 = c²

c = about 300.2

B) If a plane is going 600 km/h and it goes about 10 km that means the plane is only going for 10/600 of an hour.

10/600 is 1/60, so only a couple minutes difference.
