Notice that the 2 expressions have 2 common terms.
(r-s) is just (s-r) times (-1)
similarly
(t-s) is just (s-t) times (-1)
this means that :
(r-s) (t-s) + (s-r) (s-t)=-(s-r)[-(s-t)]+(s-r) (s-t)
the 2 minuses in the first multiplication cancel each other so we have:
-(s-r)[-(s-t)]+(s-r) (s-t)=(s-r) (s-t)+(s-r) (s-t)=2(s-r) (s-t)

Answer:
5.80 to the power of 3. I would say this is the answer if you just look closely at the number line and you will see the answer
I think the correct answer is 17
6x + 1 = 2x + 10 + 79
6x + 1 = 2x + 89
4x = 88
x = 22
