Answer:

x = 34

Step-by-step explanation:

If it is bisected, that means the angles are equal <ABD = < CBD

The triangles are equal by SAS

That means AD = CD

2x+30 = 3x-4

subtract 2x from each side

2x+30 -2x = 3x-4 -2x

30 = x-4

Add 4 to each side

3x+4 = x-4+4

34 =x

Find (r-s) (t-s) + (s-r) (s-t) for all numbers r, s, and t. (a) 0 (b) 2 (c) 2rt (d) 2(s-r) (t-s) (e) 2(r-s) (t-s)
lyudmila [28]
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:

d)<span>2(s-r) (t-s) </span>
