Answer:

The PHARYNX (throat) collects incoming air from your nose and passes it downward to your trachea (windpipe).

The trachea widens and lengthens slightly with each breath in, returning to its resting size with each breath out.

The diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it.

The bronchi become smaller the closer they get to the lung tissue

Recognize the differnce of 2 perfect squares

a²-b²=(a-b)(a+b)

so
\frac{x^2-y^2}{x-y}=\frac{(x-y)(x+y)}{x-y}=(\frac{x+y}{1})(\frac{x-y}{x-y})=(x+y)(1)=x+y

Help? (18x - 9 > 9) and (2x - 4 > -10)
4vir4ik [10]

Answer:

x>1  the  bottom graph

Step-by-step explanation:

(18x - 9 > 9) and (2x - 4 > -10)

Do the first inequality first

18x - 9 >9

Add 9 to each side

18x - 9+9 > 9+9

18x> 18

Divide each side by 18

18x/18 > 18/18

x >1

Then the second inequality

(2x - 4 > -10)

Add 4 to each side

2x-4+4>-10+4

2x>-6

Divide each side by 2

2x/2 >-6/2

x>-3

Since this is an and

x>1 and x>-3

We take the more restrictive

x>1

Thepotemich [5.8K]

Answer:

angle 1 = 51 degrees

angle 2 = 18 degrees

angle 3 = 123 degrees

angle 4 = 39 degrees

Step-by-step explanation:

angle 2 = 90-72 = 18

angle 3 = 180 - 57 = 123

angle 4 = 180 - 123 - 18 = 39

angle 1 = 90 - 39 = 51
