Answer:
![\frac{x-22}{(x+2)(x-4)}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-22%7D%7B%28x%2B2%29%28x-4%29%7D)
Step-by-step explanation:
multiply the numerator/denominator of the first fraction by (x - 4)
multiply the numerator/denominator of the second fraction by (x + 2)
this ensures that the fractions have a common denominator
- ![\frac{3}{x-4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bx-4%7D)
=
-
← subtract numerators leaving the common denominator
= ![\frac{4x-16-3x-6}{(x+2)(x-4)}](https://tex.z-dn.net/?f=%5Cfrac%7B4x-16-3x-6%7D%7B%28x%2B2%29%28x-4%29%7D)
=![\frac{x-22}{(x+2)(x-4)}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-22%7D%7B%28x%2B2%29%28x-4%29%7D)
Step-by-step explanation:
25\100*500=125
1/3*125=41.66
41.66 millilites is left in the bottle
Y² + 8y - 33 :
Break the expression into groups for formula ax²+ bx+c :
= (y²- 3y) + (11y - 33 )
Factor y from y² - 3y => y (y - 3)
Factor out 11 from 11 y - 33 => 11 (y - 3)
= y ( y- 3 ) + 11 ( y - 3 )
Factor out common term (y - 3 ) :
= ( y - 3 ) ( y + 11 )
hope this helps!
