Answer:
The answer is the first one ⇒ AAS
Step-by-step explanation:
∵ DB ⊥ AC
∴ m∠DBA = m∠DBC = 90° ⇒ (1)
∵ m∠A = m∠C ⇒ (2) given (from figure)
∵ DB is a common side in the two Δ ⇒ (3)
From (1) , (2) and (3)
∴ Δ ABD is congruent to Δ CBD ⇒ AAS
There are many answer:
1/4 is equal to 25%, .25 , 2/8 on so on. Hope this helps
Answer:
r = 44
Step-by-step explanation:
12 = r - (34 - 2)
Solve for r
___________
To solve, we need to isolate r.
Distribute the negative sign with the numbers within the parenthesis :
12 = r - 34 + 2
Add like terms :
12 = r - 32
Add 32 to both sides :
44 = r
r = 44

Answer:
6y² - 20y + 6
Step-by-step explanation:
Use FOIL method
(3y - 1)(y-3) = 3y*y + 3y*(-3) + (-1)*y + (-1)*(-3)
= 3y²- 9y - y + 3 {add the like terms}
= 3y² - 10y + 3
2(3y - 1)(y - 3) = 2 ( 3y² - 10y + 3)
= 2*3y² - 2*10y + 2*3
= 6y² - 20y + 6
