Answer:

All Real numbers

Step-by-step explanation:

c(x)= x-3

d(x) = x+3

dc(x)= (x-3)(x+3)

(a+b)(a-b)=(a^2-b^2)

dc(x) = (x^2-9)

x^2-9 is defined for all values of x , And hence the domain of cd(x) will be set of all Real Numbers

6/x-8=2/x+6 how do i solve this
lutik1710 [3]
6/(x-8)=2/(x+6)
times both sides by (x-8)(x+6)
6(x+6)=2(x-8)
distribute
6x+36=2x-16
minus 2x both sides
4x+36=-16
miinus 36 both sides
4x=-52
divide both sides by 4
x=-13
