Answer:
s can take any real value.
Step-by-step explanation:
Given that
-2(6+s)_>-15-2s
Distribute -2 over 6+s
-12-2s >= -15-2s
Simplify both the sides
Add 2s to both the sides.
We get 2s cancel out and -12>=-15 which is true.
Hence the given inequality is valid for all values of s.
This is a special case of inequality which has infinite number of solutions.
s can take any real number and this inequality is valid.
Answer:
![\frac{1}{a(a-4)}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Ba%28a-4%29%7D)
Step-by-step explanation:
Factor the denominator of the first fraction
a² - 16 ← is a difference of squares and factors as
a² - 16 = (a - 4)(a + 4), thus fraction becomes
× ![\frac{a+4}{a^2}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%2B4%7D%7Ba%5E2%7D)
Cancel the factor (a + 4) on numerator/denominator and the a and a², leaving
![\frac{1}{a(a-4)}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Ba%28a-4%29%7D)
