Answer:
a. 
b. No
Step-by-step explanation:
Given:
(3x-9) and 
=> the production of them is:
, we will use distributive law to solve this To do that. we first multiply by 3x then by -9. This is done as follows
= 
Then Open both brackets
= 
After that, we group the same terms
= 
=
(b) Is the product of (3x-9) and equal to the product of (9x-3) and
No, let find the product of (9x-3) and , we will use distributive law to solve this as the above example.
= (9x-3)
= 
=
= 
After that, we open the bracket to find the same terms
= 
= 
= 
As you can see ≠
Hope it will find you well.
Answer:
Step-by-step explanation:
1) AC⊥BD and BD bisects AC 1) given
2) AD≅DC 2) linear bisector thm.
3) ∠ADB and ∠CDB are right angles 3) perpendicular bisector thm.
4) ∠ADB ≅ ∠CDB 4) all right ∡'s are congruent
5) BD ≅ BD 5) reflexive POV
6) ΔABD ≅ ΔCBD 6) SAS
Hope this helps!
btw, I was not able to put the lines on top of some of the letters, so my apologies.
