Answer:

19.209 miles from each other.

Step-by-step explanation:

${a}^{2} + {b}^{2} = {c}^{2}$

Using this we get:

${15}^{2} + {12}^{2} = {x}^{2}$

$225 + 144 = 369 = {x}^{2}$

$\sqrt{369 } = 19.209$

$\boxed{\sf \ \ \ (-2x+-9)(1x+3)=-2x^2-15x-27 \ \ \ }$

the coefficient c is -27

Step-by-step explanation:

hello

$(-2x+-9)(1x+3)=(-2x-9)(x+3)=-2x(x+3)-9(x+3)=-2x^2-6x-9x-27\\=-2x^2-15x-27$

hope this helps
