Answer 1

Answer:

The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

Answer 2

ANSWERS:

${x }^{2} - 1$

can also be written as:

${x}^{2} - {1}^{2}$

${a}^{2} - {b}^{2} = (a + b)(a - b)$

$(x + 1)(x - 1) = 0$

$x + 1 = 0 \\ x = - 1$

$x - 1 = 0 \\ x = + 1$

therefore factor's of x are:- +1 & -1
