6h² + 82h + 120

I'm just going to simplify all of our answer choices, and see which one is correct.

a) 2(3h+ 5)(h + 12)

Simplify.

(6h + 10)(h + 12)

Simplify.

(6h · h) + (6h · 12) + (10 · h) + (10 · 12)

Simplify.

6h² + 72h + 10h + 120

Add like terms.

6h² + 82h + 120

So, A IS CORRECT.

However, let's just go through the rest just to make sure.

b) (6h + 12)(h - 10)

Simplify. Because we have already showed you the steps on how to multiply this way, I will just simplify it the faster way, without showing all of the work :)

6h² - 60h + 12h - 120

Add like terms.

6h² - 48h - 120

Therefore, B is incorrect.

c) (6h - 12)(h - 10)

Simplify.

6h² - 60h - 12h + 120

Add like terms.

6h² - 72h + 120

Therefore, C is incorrect as well.

d) (6h - 60)²

Simplify.

(6h - 60)(6h - 60)

Simplify.

36h² - 360 - 360h + 3600

Add like terms.

-324h + 3240

Therefore, D is also incorrect.

Because A is the only one that is equal to 6h² + 82h + 120, it is correct.

~Hope I helped!~

A weather plane took to the skies to measure the speed of the jet stream. The plane flew 1920 km with the jet stream as a tail w

Alex

For this case, the first thing we must do is define variables:
p: plane speed
w: wind speed
With the wind in favor, the speed is:
$p + w = 1920/2
$
With the wind against the speed is:
$p - w = 1920 / 3.2
$
Rewriting both equations, we have the following system of equations:
$p + w = 960

p - w = 600$
Then, solving the system of equations (graphically for example), we have the solution is:
$p = 780

w = 180$
Therefore, jet stream's speed:
$w = 180 km / h
$
Answer:
A) p + w = 960; p - w = 600; jet stream's speed = 180 km / h
