Step-by-step explanation:
Q~r
find k (k is the constant)
Q=kr
76=k×20
76=20k divide 20 on both sides giving you
k=3.8
then Q=k×r
Q=3.8×45
Q=171
Answer:
![\frac{2}{(x + 3)}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B%28x%20%2B%203%29%7D)
Step-by-step explanation:
![\frac{2x - 10}{x^{2} - 2x - 15}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%20-%2010%7D%7Bx%5E%7B2%7D%20-%202x%20-%2015%7D)
pull 2 from top
![\frac{2(x - 5)}{x^{2} - 2x - 15}](https://tex.z-dn.net/?f=%5Cfrac%7B2%28x%20-%205%29%7D%7Bx%5E%7B2%7D%20-%202x%20-%2015%7D)
we are looking to cancel (x-5) so will start with
(x - 5)(x + 3), selected (x+3) because the sign must be negative and must multiply to -15
now cancel (x-5)
![\frac{2}{(x + 3)}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B%28x%20%2B%203%29%7D)
